how to simulate the phase margin of <strong>switched</strong> <strong>capacitor</strong> differential amplifier (two <strong>capacitor</strong>s on each side instead of simple resistor amplifier).

I would like to know how to simulate ac response of <strong>switched</strong> <strong>capacitor</strong> circuits.

Say, I designed a bandpass filter using <strong>switched</strong> <strong>capacitor</strong> circuit technique, then how to simulate with Cadence in order to see the filter's frequency response (i.e., bode plot).
