Thank you for the wonderful lectures, they have helped me immensely. What about a scenario where you have a differential amplifier (in negative feedback) that is not amplifying a signal, like an error amplifier in a voltage regulator? It would seem that in this case you care about minimizing the output noise power and not maximizing SNR, i.e. you would want a low Gm amplifier. But I have found when you place the diff-amp in negative feedback, the input-referred noise maps directly to the output via the closed-loop gain. If the regulator is in unity feedback for example, the input referred noise does in fact appear physically right at the output! How can this be? Is this a special property of negative feedback?
@@user-ww1go3hz7n Ahh, okay. I study EXTC (electronics and telecommunication) in college, so we study some semiconductor physics, but not in such great detail.
I do electrical engineering and similar topics appear in the analog integrated circuits course If youre looking for more basic but brilliant content check out the razavi lectures

Sir, is this an undergraduate course, or a graduate course?
Seems to me as late bachelor level if that helps :)
