I designed a folded cascode op amp, when doing simulation for different temperature, I found big difference for different temperature. I never did this before, so generally how to analysis it? What is the impact of temeprature on op amp performance?
The transconductance of the input diff pair will vary with temperature. If this is a concern, you should bias it with a current source that will result in a constant gm. See page 248 of Analog Integrated Circuit Design by Johns and Martin
