Vgs is the voltage between the gate ("G") and "S," and Vds is the voltage between the drain ("D") and "S." When you first turn on the circuit, the capacitor is "empty" and has no voltage across it, so the voltage at the "G" is whatever voltage you've tapped into on the potentiometer. In your circuit, the source ("S") is connected to ground. So lots of tests left to take and reports to write for me at least. For context I'm a 23 year old chemical engineering graduate who's 2 years into a 7 year MD/PhD program.

Starting with NAND gates (in a hardware simulator) it has you build up a fully functional computer, which you then write software for. Though that link to American Amazon might not be the best based on your usage of the word "flat." I've been working my way through a different one - Essentials of Computing Systems, which I've found pretty cool. There's a book my EE friend made me buy that you might find useful for that endeavor: Practical Electronics for Inventors. In regards to printing PCBs, yeah, that's electrical engineering. So going freelance might ameliorate that problem for you. It does suck to feel like a pawn of the system - you work for pennies while other people profit immensely off of your productivity. He graduated college a few months back with a 4-year degree and now he's making $30k/year at a job he already hates after working there for a month. I was actually having a conversation with my roommate last night about work and money, etc. If you can pull it off, being your own boss is probably pretty liberating. There's definitely something to be said about being self-employed. In your case, I would probably pick up a hobbyist electronics book, like Practical Electronics for Inventors: From there it was your choice in how much deeper you wanted to go.
Similar things for BJT, but less depthĪnalog and Digital Circuits: Intro to cascode amplifiers, high frequency amplifier analysis, more detail on amplifier configurations, 6T memory structures, inverters, digital rise/fall time / timing analysis, logic gate synthesis My course mostly focused on MOSFETS - DC analysis, small signal models, basic amplifier structures. Kirchoff's voltage and current laws, node and loop analysis, basic passive circuit elements, independent and dependent voltage and current sources, Bode plots, AC analysis, time domain representation of circuits, frequency domain / complex representations of circuits, Laplace transformsĬircuits II: Diodes, operational amplifiers (black box), transistors. Unless you're an unusually motivated person, I think approaching this from the academic construct is going to be difficult. In my physics program we covered the basics of electric circuits and had a circuits lab, but really stopped short of any actual circuit analysis. Physics major here who went on to also get a BSEE, so I'm probably uniquely qualified to understand your situation.
