Re: Urgent: how to simulate the OTA with switched-capacitor
Hi, all
Somebody in this forum said that, the OTA with S/C CMFB simulation could be done by PSS, PAC...., with spectreRF, but could anyone explain the detailed procedue or just give me some documents on that? I need it badly now!
thanks a lot, and best regards
Added after 5 hours 17 minutes:
I tried two ways to find out the performance of the circuit,
1, first do .tran simulation, then use the .tran results for ac analysis
2, pss, then pac
these two ways both gave some information, for example, DC gain, phase margin, but the problem is that they are different from each other.
so could anyone tell me that which one is correct, or they should be the same?
best regards
