I want to design a opamp, which need to drive a 8p capacitor loading, and the unit frequency need 2GHz, phase margin 50.
I think if a two stage opamp with miller compensation, the second stage gm is need about 480mS,
if one stage with curent amplify, but which gain is lower and current is very large.
please give your advice, thanks!
