Much like I’m not going to say that I’ve been too busy to post anything for the past 2-3 months, I’m not going to say that I’m definitely going back to school to get an advanced degree. However, I’ve considered saying both.

Really, I’ve considered going back to school as soon as I started my first job and was dissatisfied. I mean, who hasn’t? Aside from the fact that I was previously on a co-op cycle of (work, school, work, school, and so on), I really felt nostalgic for school; I found myself saying things like: “It’s so much less work when you’re in class for a few hours a day!”, “I’ll definitely love all those new subjects I’ll be studying!”, “I’ll have lots of free time during the day to get things done and then study at night!” and many others. They’re all complete bull of course, none of those things are true for full time grad students. In fact, school can be much harder at times. I often found myself so overloaded between (continued) work and school that I would be sleeping four hours a night; plus I’m guessing I would have been sleeping those same four hours had I not been working, the waking hours would have just been spent more effectively on my classes.

The only problem now is I can’t be a full-time student.

Well, I could, but all the kinds of debt I’d get myself into would be really unrealistic for the amount I would gain from an advanced degree. Since buying and fixing up my home last winter, I have taken on some markedly adult-like responsibilities in my life. And so I began investigating options. Going back to school is not something that I take lightly, nor should anyone out there; in the event that I make it back to school in the near future, it will be a long slog through homeworks and tests and unrealistic deadlines and the such. And all for a piece of paper. Luckily I had some great advice about school/work/life balance from my former boss and mentor:

Based on my experience, I would say make sure that all of your house projects are complete before you start and don’t plan on starting any new projects until you get your degrees (both of ‘em!). Also make sure your personal life is well-organized and in good working order. Don’t take in any more dogs, cats, or other mammals. You may also need to (*gasp*) scale back your musical activities.

While he was obviously joking about certain things there (no more music??), I take his advice to heart; I’ve also seen similar behavior from co-workers who are also in school right now. You really have to throw yourself into studies to get the most out of it. I think my perspective now that I’ve been out in the working world for a while will really allow me to succeed, both in the things I have already learned and how I approach problems.

The first kind of decision I will need to make is what kind of Master’s degree I would want to attain. I was actually quite surprised there was even more than one option available. The first degree I think most people think of in Electrical Engineering is an Masters of Science in Electrical Engineering (MSEE of MScEE). I already missed the boat on the BS/MS program that my alma mater offered; this was a program that allowed students to automatically segue from their undergraduate studies into an advanced degree, often taking Master’s courses early to help push the amount of time spent on the MS down to 1 year. So the next option I could have done was go back to school for a Master’s degree (the normal way) and then write a thesis at the completion of my studies. This would likely involve research with a faculty member and the thesis would be based around that research. I doubt this option would be possible for me, because of the aforementioned house, mortgage and “grown-up” responsibilities, up to and including my job (which I wouldn’t want to give up either). Yet another option would be a “project-only” MSEE offered at some schools that would involve the same coursework as any other master’s degree; however, the thesis would be replaced with a project, possibly in conjunction with day-job projects (but probably segmented in some way or another). At the programs I am looking at, this option is only allowed when working full time and going to school part time; luckily, that is one of my few options. The other interesting option is something that is called a “Master’s of Engineering” (in Electrical Engineering in this case). My alma mater offers such a degree (abbreviated as “MEng”) and has a streamlined course offering for engineers in my situation. The degree leans more towards mixing business and science, as many engineers do on a daily basis. In that regard, it could be a very helpful degree, in the event it imparts the necessary business acumen to get by in the hard business world. However, I question the degree and how it would be viewed in the working world once I am finished:

• Will employers view it as a lesser degree if I try to stay in the technical field?
• Will a MEng degree limit where I can go in my career?
• Do I ever want to get a PhD or am I OK with a “terminal degree” such as an MEng?
• Will I be able to learn all the technical things in a more balanced program such as the MEng?

I’ve also been considering which schools I would even be able to attend. Thanks to the digital age, commuting distances have been shortened to only the time it takes for light to travel down a wire. What that means for John Q Public-school-graduate such as myself is that a lot more schools are now accessible to a full time worker. And not just the University of Phoenix here either. We’re talking top 50 engineering schools. Who you ask? How about:

1. Stanford
2. Georgia Tech
3. Purdue
4. University of Florida

Even those four provide a pretty heavy hitting list of top research institutions offering the course work entirely online. Sure, this might be a more difficult way to collaborate with others in your class or work on projects or communicate with the teacher; but it also means that geographical barriers are becoming less and less of an issue. If I had an online electronics store that I ran out of a shack in the backwoods of North Carolina, I could now attend the number 2 engineering school in the country just as well as someone living in Palo Alto (assuming I was accepted). So while I do have a wonderful institution and my alma mater in my backyard (CWRU), I also have more options and more specialized coursework for whatever branch of EE I would like to explore more.

So what next? I guess now I have to take the GRE and get applying (and eventually figure out how I would pay for it all…). As much as I’ve thought about the potential convenience of going to an online version of a school, it’s applying just like any other Master’s Student. So really the online programs are more like you’re enrolled at the school, you just can’t ever make it to class because you’re sick all the time; plus the professors are nice enough to send home your schoolwork (but not in a folder like back in elementary school days).

In the coming weeks/months/years (who knows?), I’ll try not to write about school plans too much. However,  think there are some issues that merit discusion on here and elsewhere (and hey, I like getting help from people responding in the comments). I’ll probably write at least once about my potential area of studies (should they be similar to what I’m doing right now? Should they be more towards my interest in DSP?). I’d really love feedback from anyone that happens to read this, especially students who went back to school after being in the working world for a while. Please leave any tips or tricks you might have in the comments.

Clarification: When I write “work a job fair”, I mean how to get the most out of it as a student or job seeker. This could be confused with the fact that I sometimes recruit at job fairs, but I thought this should be brought up at the beginning after I re-read the article.

In talking to a fellow engineer about to attend a career fair, I realized I had some advice for him, having gone so many times in the past. I’ve even been back a few times to recruit for my current company and being on the other side of the handshake is an interesting insight into the do’s and don’ts.

1. As soon as you realize they want you to apply online, ditch.
   • First off, this was a pet peeve of mine as an attendee and is to this day. As soon as HR departments at large companies realized they could just use computers to filter the resumes of prospective employees instead of reading them (yeah, I’m looking at you Big Blue), they did it as fast as they could. The result was that you now walk around job fairs talking to people and handing out resumes, only to assume those people will be throwing it away ten minutes later (“Why did I print that on paper that costs 50 cents a sheet?!?”). In the event you’re talking to someone from a company and you even overhear a different recruiter asking someone to apply online (assuming you hear it before you’re told directly to do so), kindly end the conversation with the person you’re talking to and write in your notes to apply later. Job fairs are to make first impressions; if the employers’ representatives are not taking notes on the people they are talking to, they really are only wasting your time.
2. Be excited
   • Enthusiasm is contagious. It can make any conversation more exciting and in the case of the recruiters, less routine. They have many of the same conversations over and over throughout the day, often with people that don’t show particular enthusiasm for what they are talking about. More importantly, enthusiasm about your chosen field is a precursor to another trait that I feel is particularly important in any field: passion. Without it, you probably won’t be able to hold your interest long enough to become an expert in your field. And I mean a real expert, not like those silly people online that start blogs and call themselves experts. Haha.
3. Be excited, but show a little modesty
   • Before you go off the rails and start spouting all of your best characteristics to a potential employer, remember a few things:
     1. Designing something in school is much different than designing something in the real world.
     2. No one wants to hear every single detail of your design project upon first meeting you.
     3. As an engineer, getting a design job just out of school is difficult and unlikely. The majority of engineers use their degree to launch into other types of jobs. I’m not saying you shouldn’t shoot for a design job if you want one, I’m just saying the expectation shouldn’t be that you will be handed one (and you should keep your mind open to all opportunities).
     4. If you present your past work correctly, the work will speak for itself. In fact, succinctly describing your achievements in an understandable way will help to show your enthusiasm much better than you trying to squeeze 500 words into a 1 minute time period. Show them that you are really proficient in the area you’re targeting and you’ll get recruiters clamoring to know how much you really know (and eventually what it’ll take to get you on their team).
4. Forget the give-aways
   • The pens and t-shirts and yo-yo’s and other stuff they give away at these events are fun to get and sometimes quirky, but essentially worthless. If you want to get free stuff with a logo on it, go get the job from the company and worry about the branded crap later. Focus your time and resources on meeting people, not collecting widgets.
5. Figure out what skills they’re looking for
   • No amount of preparatory work researching the companies you’re targeting will let you know what skills a company is looking for. Hell, it’s in the company’s interest to be vague when they list what kind of employee they’re looking for so the maximum number of people will stop by their booth. This is one of your most important tasks at career fairs; in fact, it’s one of the few reasons to stick around and continue talking to a representative from a company once you have found out they only accept applications online. Talk to the engineers that work in groups you would want to work in (wait to talk to them if there is a line) and find out what they look for in potential candidates. In fact, ask them that, “What do you look for in potential candidates who would be hired for YOUR position?”. It might sound a little weird, like you want to replace them with yourself, but it’s the most direct way to know what skills and techniques you need to have to work there. If you have those skills, awesome. If you don’t, work on getting those skills, however you can.
6. Know what you like and don’t like and tell them about it
   • This hearkens back to being enthused about the field you’re studying. In the event you’re not very capable in transmitting your enthusiasm to the person you’re talking to, stating what you do and don’t like can help to showcase what you’re really trying to do with your career. But it’s also important because you can narrow down the companies that can actually offer you a job. If you’re really interested in embedded systems but you’re talking to  a company that only works on designing silicon, stating what you’re interested in can be a real time saver. If you’re not particularly fond of working on spreadsheets or databases and you say so, you can quickly be informed by the company you’re talking to that those things would be the main job function of any potential employees. In stating what you really like and dislike, you basically turn a career fair into a speed-dating service, quickly going through all of the options at a particular event and honing in on those that have real potential.
7. Brush your teeth. Wear a clean shirt. Don’t be a robot.
   • I only wish this was more obvious to people than it is. I’ve already been pointing out that career fairs are only as useful as the impressions you make on potential employers; sometimes it’s also about the resume you hand them.  But if the whole ordeal is about impressions, some people don’t get it. Look decent, smell decent, smile decent. These are all things that are easy but immediately put you out of the running if you get them wrong. Remember the lollipop first question for $100 on “Who Wants to be a Millionaire”? Remember some of the dodos who got it wrong and had to immediately leave the stage? Don’t be one of them.

Do I know everything about job fairs? No, I know very little. I personally never really liked them as a potential employee. I’d rather stand out to an employer  by connecting on a personal level with a recruiter and then showcasing what I know. There just isn’t time for that at career fairs. But if you or the employers you’re interested in working for consider career fairs a necessary evil, I think the tips listed above can have a positive effect on some of your interactions.

What kinds of things do you try to do at job/career fairs? Can those things be done by engineers at career fairs or are they specific to another profession? Please let us know in the comments.

Although I’ve been busy working on Electricio.us lately (thereby neglecting this site), I have been able to continue listening to my local NPR station (which, like any good nerd, I love). A program the other day spoke to a local community trying to build up the economy through the arts.

I was intrigued. I had never thought of that before. Why would anyone ever try to develop an arts community first? Where are the jobs? Well folks, we have a bona fide Chicken and Egg paradox here. It really goes both ways. What happens if a community only has day jobs and no culture? What happens if you develop a thriving arts community before there are “Economic Drivers” and jobs for people moving there?  Does the absence of one element slow the growth of the other?

I would tend to think the jobs come first. And of course when I think jobs I think of technical jobs, not those silly financial jobs that got us into this mess of a recession. I mostly think of technical jobs first because I’ve never really experienced anything else and I’ve heard technical jobs can have a multiplicative effect (helping to create some of the other jobs I’m not as fond of). But what happens in locations where there are only jobs and no culture to go along with it? Who really wants to live there?

An example is contained within Eric Weiner’s book, The Geography of Bliss (which I first read about at Get Rich Slowly). He is traveling the world, looking to explain why some locales are happier than others. In the midst of his travels, he goes to Qatar (one of the richest regions in the world) where he encounters a city booming with jobs (mostly for migrant workers) to fill the “need” of those rich from petrodollars. However, he notes the absence of culture and even references how the richest from that country travel the world buying up impressive art collections in a hope to obtain culture. The result is a city full of people being shuttled to and from chain restaurants and malls, without any interesting things in between. Even the history museum is filled with artifacts toil and struggle in the desert…and not much else. Because the jobs in the region are scarce, no one really wants to be there, but no one working there can really leave.

The other extreme is when a city has a strong art and culture community but is lacking in jobs. An example is New York City in the current recession. Even though the current unemployment numbers are hovering around 10.3%, people continue to move to the city. Why? Because you can’t find many other places in the world with a similar art and culture scene. Where else can you find so many museums in a 10 mile radius? But when it comes to being practical? No, not so much. The fact that the unemployment is only 10.3% is likely because of the high costs associated with living in or even near the city.

So back to the original example. Would starting an arts community allow for eventual development of a thriving economy? It depends. Are there other nearby communities that can feed into this new community? Are those other communities lacking in culture or interesting events of their own, thereby necessitating people in that community to travel? Are there people in the existing community that will be benefactors to the new community? And most importantly, are there people willing to move to and develop a new arts and culture based community?

If there is a willing population, both moving to and surrounding a new (or revitalized) community, then I believe it would be possible to use arts and culture to build up a local economy. I think that it is a non-standard way to draw young and artistic people into a new place and to centralize events and gatherings; this, in turn, could help to draw people that aren’t contributing to the art and cultural scene directly but want to experience and patronize it. I know that Cleveland, with excessive sprawl and thinly populated suburbs, could really benefit from a community such as this (really it will be supplementing many other creative and culturally rich regions). Although the travel required between regions is undesirable, I think creating an arts community can really help to bring people together, which is really what drives economic growth over the long term. Do I think there will ever be large corporations moving in and bringing thousands of jobs to this revitalized community? No, I don’t; but that’s not really the point anyway.

I’m interested to know if anyone has heard of other communities built first around cultural and artistic endeavors that later blossomed into vibrant communities. If you have ever heard of one or have an opinion about what they’re trying in Cleveland, please leave a note in the comments.

I had an interesting conversation today with a few friends about the exodus of young people from the workplace back to school during this recession. It seems as though people in Generation Y are bailing left and right on current jobs and diving back under the safe covers of academia. And who can blame them? You get to work on interesting research (hopefully), you get a stipend (maybe) and you have better prospects when you’re all done (eh, doubtful). But that leads me to ask, “Who’s going to do all the work when the economy is in full swing again?” Let’s survey the current demographics, starting from the top:

• The bosses — Not to sound deriding, but they aren’t doing the type of work I’m talking about here. The never have and never will…mostly because they actually have better things to do. For real. They have to meet with other big wigs and figure out where to steer the company and where the market is going and hopefully how to react in time. The work I talk about is more a “down-in-the-trenches” kind of work and I never really expected them to do that kind of work, just thought it was necessary to actually start at the top.
• The elders — The elders are those who aren’t necessarily in charge but those that have been around for a long time and really understand how a company or industry works. They won’t be doing the work when the economy recovers…because they’ll be retiring. Think about it. How many people were likely planning on retiring in 2008 onwards who suddenly saw their investments vaporize? No, they decided they better stick it out. And though they won’t see a huge return to the days where their portfolios were bulging, I would venture a guess that if the conditions are good enough and they feel that they can squeak by on portfolio growth after they retire, a lot will take the out. If you’re pushing into your 70s, I’m guessing you’re ready for a break. Even if they stay on part time, they won’t be doing the grunt work.
• The smart ones — The smart ones are those that drive ideas and new products. Even though they may have been around and producing good work for a while, they aren’t allowed to go anywhere. They are the geese with the golden eggs. Where would they go anyway? The people in charge of promoting them would have to replace themselves. Not likely. So they will have to do some work still, but you can probably watch for this group eying the social security line on their weekly pay stub longingly and starting to stick a pinky toe out the door. If you’re looking for a technical mentor, get ‘em before they’re gone.
• The middle — The middle is all those people that were doing the grunt work 20 years ago and did a good job. They may have run out of salary headroom and jumped over to management or maybe they needed a new challenge (I can only imagine dealing with engineers or other similar underlings from a management perspective every day). Either way, there’s little likelihood they’re planning on stepping back into lesser roles. No, they have their eyes on the upper management jobs of the elders and the other aging boomers.
• The lazy ones — They were the ones on the team that did work every once in a while but in general only contributed when the workload really picked up. They were the auxiliary fuel tank of your company as an airplane–useful when you need it but really just weighing things down when not in use. And although we know it’s not really true, we have an inkling some of them got the ax when it fell last year. Even if you were deluded enough to believe that all the dead weight in your company was gone, the ones in this category that aren’t gone are really good at two things: not doing work and looking like they are. Count them out.
• The young upstarts – This group has a shot at doing some of the beefy work. In fact, this group has the highest likelihood of doing the majority of the work. I should mention I also feel as though I am a part of this group and therefore have a lot of interest in studying it. “What’s that?? Jim, Allison and Mark are all going back to school? Why? Trudy is going too? What the heck? Who’s going to do their work?!?”, you say (the answer: whoever is asking that question). This newfound love of the classroom is the other reason I am interested in my own demographic. We’re all jumping ship hoping to leapfrog into the next part of our career! There doesn’t seem to be any paying of dues, does there? Welp, that’s because there isn’t. But you can’t do anything about it because everyone in this demographic is back in classes learning about managerial accounting or tort law and not actually doing any work. Now the real question: when everyone pops out of school at the end of the recession, who will be better prepared? MBA Marty or Experienced Eddy? I’d be inclined to say the second, but again, I’m biased here. If you’re in this group and not going back to school, expect more work coming your way. Lawyer Larry is busy studying.
• The new grads — Quick! We’re running out of people that have any interest in engineering and menial tasks! Get me some workers! “Waaaaaait a second,” says Bob the manager. “All we’ve got is the new grads. There’s no way I’m hiring them without any experience.” Well Bob, too bad, you’re running out of options. Just hire these new kids and try and push them to learn faster and work harder. And do this even though those new grads have higher expectations of what employers will give them and the hours they are asked to work. You’ll probably end up giving it to them too, because what other options do you have?
• The overseas workers — Well, there’s your answer. It’s really been more of a circular process, figuring out who will be doing all the work. Think about what’s been said and how people have reacted. “Foreign labor is taking all of our jobs!”, the workers said at the beginning. Then they thought, “Oh! I better go back to school and learn how to manage people overseas and the remaining labor in the US!”. Then they get out of school three years later, lobby for a shiny new management position and ask “Ok, where are my underlings? Hunh? No underlings?!? Well crap, hire more foreign workers, we need to get this project out the door!”. Lather, rinse, repeat.

I want to be clear about a few things. First, I don’t disagree with going back to school. I plan on doing it myself some day, in some capacity. I just disagree with the timing. I liken going back now to pulling all your investments out of the market at the lowest point back in March (maybe to pay for school?). You remove yourself from the market at a time when the most growth can occur. You remove yourself from situations that include working long hours on hard work but it’s with a team that affords you more responsibilities. I feel that the next few years will provide some great opportunities for innovation and growth in certain positions and companies. Second, I realize that some people are going back to revamp skills, especially when they feel that they cannot find employment. This is understandable and expected based on enrollment numbers from past recessions. I would only remind these people to remember to keep up their real-world skills so they can be hired right out of school. Academia doesn’t have room to hold onto you and they have a similar hierarchy as above except for one catch: those tenured professors don’t plan on giving up their cushy position until they are forced to or decide to leave on their own. If you do choose the academic track, get a comfy couch to wait/sleep/eat/live on. Finally, I’d like to speak to my targeting of MBA and Law degrees. It’s not that I think they aren’t important, because I feel that a lot of really important concepts are taught in both management and law classes. I mostly take offense to the idea of you being my boss in 5 years because of a piece of paper. I respect the people around me who are working hard and have better vision than I do to tell me what to do. If you plan on “managing” me without first working by my side or in a similar position, expect to work extra hard to gain my respect.

I believe the solution here is what a lot of people are actually doing: sitting tight and getting some work done. You need to continue to show your company you are a valuable and contributing member while maintaining boundaries on how many peoples’ work you are willing to do. It sometimes seems bleak when you see others stagnating in their career progression right in front of or next to you. However, I believe hard work and tangible results will be the true indicator or advancement and success whenever the economy rebounds. If you think your hard work should go towards a more noble cause, strike out on your own. If companies end up short on talent when the economy comes back, a savvy consultant could be flexible and fluid enough to be exactly the solution customers and companies are looking for.

Irony is having a blog post in your queue with a title such as this one and just sitting on it for weeks on end. Luckily I’ve been trying some things instead of studying them, it just so happens that those things have nothing to do with this site. I hope to discuss those on this site soon.

I am a glutton for knowledge.  Part of it is my fear of looking silly in front of co-workers when I don’t know the answer to something. Part of it is feeling like my knowledge base is lacking and the thought that I can always learn or teach myself something new. But when presented with a new challenging situation that requires you to learn the question is always the same: where do you start? Do you jump in and try it out? Or sit back and study what others have tried so as to not duplicate their mistakes?

There are two extremes

1. You study so much and try to take in so much that you become paralyzed by information
   • I feel like this happens to Generation Y more than other generations. Not because we are dumber than others. Instead, I think we are so accustomed to having all of the necessary knowledge required to solve a problem at our fingertips (i.e. Internet, ChrisGammell.com, etc).
   • Academic thought processes often begin with simplistic assumptions about the model you’re considering. Analyzing these over and over can be very time consuming and can quickly become too complex to handle. Even analyzing the minutiae associated with a single transistor can be mind boggling. What happens when you try and expand that knowledge to 10, 10k or 10M transistors?
   • You over simulate, over analyze, over think a problem past the point of diminishing returns. An example would be designing a new type of toothbrush. You can model the toothbrush, the bristles, the handle, the shapes, everything; you can even go out and get ideas from your toothy customers about what they think they would like or dislike about your design. But until you prototype your new type of toothbrush and put it through testing (product testing, tooth scrubbing ability, will it shatter in someone’s mouth), then all of the testing and surveying in the world won’t matter.
2. You have little knowledge of a problem or situation that you just start changing stuff randomly and keep changing until something works…without realizing the consequences.
   • This seems to be the modus operandi of the inexperienced, but not necessarily the uneducated. A gutsy, recently graduated electrical engineer may emerge from the cocoon of the academic environment ready to go out and change the world. And every resistor value of a circuit board they encounter. And mess with the capacitors. And change the model of the op amps. Oh, and don’t forget to swap out transistors. “What?? It still doesn’t work? But why?”
   • This can be as much a symptom of engineering bravado as it is bad conditioning. If the person involved has always had simple problems placed in front of them that have obvious or at least semi-obvious solutions (ahem, most introductory electronics labs), they will fix the “broken” component and pat themselves on the back. In the real world, that “broken” component isn’t broken at all. It’s just out of spec and you can’t figure out for the life of you why that unit you’re testing refuses to turn on anymore after increasing 5 degrees internal temperature.
   • You forget/refuse to read the manual. Granted, some of the greatest “tinkerers” out there can just magically turn a knob and get a broken piece of equipment to work. But the reason they can do that is because they actually turned the wrong knob about 1000 times the last time they tried to fix something like this and that knob did absolutely nothing.

A Good Mix (for me, at least):

[STUDY] My own personal mix when it comes to circuit problems starts with the problem definition. Understanding the problem is so much more important than what you study, how long you study it or how you begin to test out your ideas for how to fix it. If you don’t understand what the real problem is all that later work is for nothing! However, I try to understand the issue without going overboard and trying to understand every single minute detail; this could be just as bad as studying a possible solution for hours on end.

[TRY] Once I have a grasp on what the problem is, I try the obvious stuff. You’d be surprised how often it can be the really dumb things that trip you up. And those might not even be the problem you’re trying to fix. You could try to troubleshoot a blank screen for 20 minutes, throwing your best ideas and debugging techniques at it before you realize, “Whoops!” you never plugged in the display cable. Or you can’t get your software to work once you load it onto your electromechanical whizzbang toy…but you actually loaded the wrong version of the software or the toy doesn’t have any batteries in it. The silly things will waste your time and throw you off the trail of the real problem if you’re not careful.

[STUDY] Next is researching the problem to see if it has happened before. Some of you out there will have unique situations, like making a new analog chip that no one has ever made before. But I’d guess more of you will be encountering problems that can be researched. Even the analog chip designers will see issues that are similar on some level to other products or models within a corporation. Oftentimes the best troubleshooters are those who are able to compartmentalize problems and then analyze where those problems came from and research how others have fixed it in the past. I’d rather have a boring problem that someone else can easily tell me how to fix than one that I can’t figure out at all.

[TRY] After trying and then studying all of the really obvious stuff, I start to go back to my resources–either online or in print–and start to search for information on the topic. Obviously the online information is much easier to search, but I also have some trusted books that I turn to on a regular basis. I might see a chunk of a circuit that looks familiar and try flipping through the pages to see if I can’t find a similar circuit. If that doesn’t work or the circuit looks extremely foreign to me, I’ll go back and study some of the basic properties of the components within the circuit to see if there might be a certain property the designer used that I have overlooked. And if all else fails, I’ll start to ask around to try and gather others’ knowledge of the circuit. True, this isn’t quite studying, but can often be more effective. I try and balance asking others for assistance only after I have tried to solve the problem on my own and not made any progress. I think it is important for my personal growth to struggle with a circuit before asking for help and I think it’s important to not get in the habit of running off and asking for an answer so I don’t waste the other person’s time. However, I don’t want to be so stubborn that I waste my time and the time of those who are paying me.

[STUDY] Alright, so now you know what the circuit is and how it sort of works. But you also know that you need to change the circuit in order to make it work better. What now? Next I would try and write out any equations I know that are relevant to the circuit. Not necessarily any equation, that could end up being a waste of time. Keep it simple and make sure you know where the currents and voltages are in different parts of the circuit. If there are components (such as capacitors) in the circuit, include basic equations that can help to describe their behavior. If you don’t need 3 chalkboards to do so, try and figure out the transfer function (relationship from input to output). If you have a circuit that is too complicated either break it down into smaller pieces and try and figure out the transfer function or take the plunge and try it out in SPICE. This will help you to better understand how the circuit might behave when presented with certain inputs. All of these exercises are done in order to present you with a solid starting ground for when you actually construct the circuit, so you know what to look for and what behaviors to expect.

[TRY] After all of the studying and simulating and pondering about this circuit, you should have at least enough knowledge to begin building up and trying the circuit. This is an important step in any circuit creation process because of the nuances the real circuit will show you. Perhaps you forgot to model a realistic op amp in your SPICE simulation and it was outputting 500 A. Perhaps you didn’t realize in your equations that a resistor will have different properties depending on how much current you actually put through it and that your circuit happens to be particularly susceptible to those changes. Perhaps you completely disregarded a simple concept such as bandwidth and your circuit is now oscillating so hard it breaks. All of these things will be uncovered when you begin to build up your circuit and try out different inputs. Once you realize what some of the realistic problems are you can go back and modify your assumptions and models and start to delve into whatever topics you believe will get your circuit to the optimum operating point.

Finding the right balance between slowing down and taking your time to figure out a circuit or jumping in and seeing what works can be a fine art. Sometimes projects are on a very tight schedule and need a product cranked out the next day (think startup). Sometimes you have one shot at making a final product or else your company will fail (think chip fabrication). Finding your own personal mix will take time and trial and error.

What is your personal mix of trying vs. studying that gets the best results? Leave your tips and tricks in the comments!
