Click For Summary
Multiple amplifier stages are essential in electronic circuits to enhance signal gain while maintaining stability and minimizing distortion. Using stages allows for better control over gain-bandwidth trade-offs, as high gain in a single stage can lead to instability and oscillation. Negative feedback can improve DC stability but may degrade dynamic stability, necessitating a careful balance in design. Amplifier stages also enable the use of techniques like Darlington pairs to increase current output without compromising performance. Overall, the design of amplifier circuits involves navigating various trade-offs to achieve optimal functionality.

LvW, what makes you think your questions have more priority than anyone else? I don't believe you have asked me a direct question so it would be pretty hard for me to answer. I don't believe I ever said you are "most outright wrong". I have seen what I have seen and I know what I know. It would have been nice to resolve this with a simple admission from one side or the other that phase margin or something else is being considered by one side and not the other. What a waste this has turned into.

Edit: I believe milesyoung was the first to ask a question besides the original poster. Wouldn't it be logical that his question is answered first?

Averagesupernova - please, excuse me. As far as the statement "most outright wrong" is concerned, I have I have mixed milesyoung`s answer (post#25) with one of your answers. I am sorry for that.
Nevertheless, I do not like to continue this (slightly aggressive) "discussion" - and it does not help the OP at all.
As far as the technical aspects are concerned, I just have said everything I wanted to say.
Bye bye.
LvW

My excuses about the late respond. I was away for a bit and couldn't chat back. My thanks to all of you who answered to this thread. Thank you!
