Designing Discrete OpAmp (Read 4453 times)

soso New Member Offline Posts: 8	Designing Discrete OpAmp Jun 21^st, 2016, 11:56pm I am trying to analyse a discrete differential amplifier circuit by answering some question. I have done the analysis of the input stage, I would appreciate if I can get some feedback on my approach. Kind regards

Also, why not just do a small signal model at the bias point?
