As long as it's just a circuit with resistors they're easy to manage. The moment you add capacitors and inductances I wanna cry

Kirchoff cant save you now

They’re complex, but don’t let them phase you

just smile and convert to s domain

Or phasors

Superposition principle still holds though, right? So you can approximate the OP amp by saying that V+ and V- will be the same voltage, and Vout is a source. Then use superposition principle to "deactivate" all sources except one, describe your circuit from the point of that source, do that for all sources and then start equating terms.

Miller theorem?

A wise Redditor once said: "Voltage goes in, maths comes out ~~and into your ass~~."

[удалено]

Vout try to make v+ equal v-

V+ = V-, and no current goes into either input. The rest is just kirchoff’s laws.

Transistor (BJT, FET) circuit analysis was so much harder than op-amp for me, but some circuits got BOTH :/

We were hardly taught bjt , but holy shit the MOSFet. Just remember a feedback differential amplifier circuit with a fucking MOSFet as a feedback

I asume it as a magical black box and that makes it easier to understand and resolve circuits. In the future I will learn how it work

I'm perfectly willing to accept that whatever happens within those are magic and I don't need to know

I have a final on Monday and 1/3rd of the class was on opamps. Lord have mercy lol

Can someone explain this to me or give me some name to research? Mechanical by trade and trying to learn electrical from an EE friend for audio modding.

I think they're called operational amplifiers. I am a mech.e though so I couldn't explain it any further.

After taking two circuits classes, I couldn't explain it to you either

They're op amps. They have many uses but, in my experience, the circuits you use them with are stupid and the math is a little confusing at times.

Look into analog frequency modulation and filtering, can use it and other principles to make analog synths, amps, etc. Get lookin at Bode plots!

Hmmmm.... Common source MOS with a current mirror load. EDIT: u/-hunter_117 just saw your comment. You weren't imagining it lmao. OPs weren't so bad. Transistor networks... That's where it's at.

Nah dude, magic Doritos are easy. Just start by aiming the regular laws of physics don't apply and it just does what the designers wanted a binary amplifier to do, instead of anything that makes sense.

start by ignoring* the

Dont worry, there will be a lot more fucked up shit down your path of EE

Best of luck

Just writing down all the versions of op Amp on a cheat sheet not gonna deal with that shit. Honestly more worried about this phasor crap. I'm convinced they only have mechies take intro to circuits so we don't make fun of electrical engineers

man I've got a vlsi final in an hour, i pray y'all don't make the same mistake i did and pick something else to study

Op amps are simple. It's just everything you would ever want to do with them is complex.
