How Do Op-Amps Work?

Support the channel! :)

You may (or may not!) know the 'golden rules' for op-amps. A few simplifying rules that allow us to analyse many op-amp circuits with ease. But do you know WHY those rules work? What is going on inside an op-amp? Lets have a look!

This is the best explanation of op-amps i have ever seen!!

I’m actually surprised this channel don’t have more traffic. It’s up there with “SimplyPut” in my book. Keep up your sharing and passion for electronics. I’ve learned lots from channels like these. It drives me to do the same. Thanks Bunches.

Super helpful, very happy I found this channel

I never really attempted to understand the inner workings of an op amp before, but you made it seem so approachable!

I am late to this party, but thank you got sharing your knowledge, I'm on the verge of understanding some of it!

All clean over my head, looking to see how op amps work, none the wiser for watching this video.

Phucking brilliant!

I understand how it works for AC case, but how it is possible that it amplifies also small DC voltage? Where is the clue which enables that?

Having Harry Potter explain electronic circuits is strangely comforting

When I replace Q7 pnp by npn with all necessary changes for R17 and R18 it does not work. Why???

Hey G would you make me a sandwich

OK, except grabbing the nose. It is not esthetical. The rest is very good.
