simulate sc cmfb dc

Should I use pss and pxf in spectre?
Or just use ac and dc simulation to find the gain and phase margin?
Could someone give me some help?

Besides that, I can't measure the ocmr and icmr of the fully differential amplifier

Thanks in advance.

Use PSS & PAC simulation. You can use PNoise for noise analyses.

Refer to Ken Kundert's article about the simulation of SC-filters at www.designers-guide.com/Analysis

I did not understand why you can't get input and output common mode range.
 

So I should learn PSS & PAC first.

If anyone have some step-by-step files. Could you mail to me?

Thanks a lot!

dude y dont u make a behavioral model (using V and VCVS components) of ur CMFB ckt and do an ac/dc analysis of opamp with that..it will alow u to simulate and verify ur OCMR and ICMR stuff..
