Hi friends
As you know, there is 2 types of CMFB, one for continuous time and the other for switch capacitor(for switch capacitor application).
which one is good for OPAMP of stages?

Hi every body
i got some nice notes for designing folded cascode OPAMP with CMFB switch capacitor
i hope are useful for every one
many thanks
Well, as far as I know,continuous CMFB can not be used in SC circuits because switch will induce high frequence noise which continuous CMFB can not deal with.
