i design a switched capacitor integrator
first i design amplifier and Dc and ac analysis it was
I plot diagram of the 20db amplifier gain with ac gain and phase (direct plot)
but with this way ( ac analys and then ac gain and phase ) i can not plot correct gain diagram for
switched capacitor integrator

How do I calculate the gain ?
 

I am not familiar with Spectre - and, hence, I know nothing about it´s capability to analyze S/C circuits in the frequency domain.
However, all other simulation packages known to me (LT-Spice, PSpice, TopSpice, ...) are able to analyze the frequency response of S/C circuits (time discrete systems) only after the circuit has been transferred into a time-continuous equivalent. In particular, each switched capacitor is to be replaced by an artificial element with delay.
