hi,
i have designed OP OTA for SCA and now i don't how to simulate my SCA, could some one suggest me efficient way to do that, or maybe any artical or paper.
after i finish my thesis i will try to make one report for those people interested in this area to learn the good steps for making OTA, my one 1.2v with highe performance.
other thing i wnat ask about what is the relation ship between Fclock and frequency of sampling, they are equal?

thanx in advanced
regards
 

when you measure the ac response of SCA, use a ideal cmfb circuit or a CT cmfb amplifier to stabilize the differentail outputs; after ac simulation, put the SCA into a system to simulate the transiet response.
sampling frequency is the frequency of the clock controlling the switches of SC circuit; the Fclock? maybe alternative denotation for sampling clock.

Cadence's spectreRF can do the job.
