Title: Designing Discrete OpAmp Post by soso on Jun 21st, 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 |

Title: Re: Designing Discrete OpAmp Post by loose-electron on Jul 6th, 2016, 10:28pm You need to look at 3 solutions - high common mode voltage, low C M V and middle range they are 3 different things. Also, why not just do a small signal model at the bias point? |
