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. jack[/b]

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.

Could you mail to me? My E-mail is mcjackson@163.com Thanks a lot! jack
