Hello, Sheldon
Thanks for your help. Like you said, adding another SC stage is helpful to reduce the charge injection which goes out to the output terminal of the 1st SC. I should tell my problem specifically. I care about the effect of charge injection at the input or so-called residual offset. When simulating a preamp with an ideal clock(Gswitch in HSPICE)for auto zeroing, there is no charge injection. However, replace an ideal clock with real mos switches, an error is found out. Regards,
