HI Aaron Your videos are such great resources and I like your explanations. Thanks to these videos for cementing and removing some of the pitfalls in my knowledge during my bachelor thesis project that I just finished with flying colors two days ago.
Aaron, Thank you so much for ALL of your videos and the education you have provided us. A dummy like me needs all the help I can get. Foolish as it is I am trying to learn to repair electronics as fast as I can. I have so much to repair around here and would like to help others keep their gear working for as long as possible. Also, A fully "Differential Amplifier" would sound pretty good in my audio system! 😁😁😁
Differential amplifiers have always been a weak spot in my understanding of transistor circuits, and lately I've been working to rectify that. Thanks for posting this video! Now for my question. At 4:32, what determines that the left transistor is a CC amplifier (as opposed to CE), given that it also has a resistor (and an output) in the collector leg of the circuit? Is it a matter of degree, since there's resistance in the emitter leg as well?
Great explanation, thanks for the efforts, one doubt though…at 7:17 you mention that RE is in parallel with re (from T2), but in fact RE is tied to -VEE, whereas re(from T2) is tied to ground, what assumption was made to consider they are in parallel?,
All of these assume well matched parts and beta. Things can get dicey with different batch parts as beta can be off by huge amounts. Might be good idea to bin parts before starting so you don't tear out your hair trying to figure out what went wrong.

Great teacher. Thanks.
Such a great video for electronics learners. Thanks for sharing.
Excellent operational amplifier tutorial, thank you.
Thanks for your great videos. It reminds me of the fundamental EE topics I did 40+ years ago at university.

Hi Aaron,
Great explanation!
I would like to have your all books!

How about a detailed and complete analysis of the 990 discrete op-amp

I will try building one next week.... It sounds fun, that I can control the parameters of my op-amp

Are you reading my mind? 😂exactly what i was looking for😀
Great derivations. However, frequent pausing of the video is needed to digest all that's presented here.
