AC analysis of switched capacitor filters

How to analysis the AC behaviour of Switched capacitors filters ?..Since a part of it is in didgital domain.i..e feedback is not continous because of the switches used...

You can build average model for SCF and simulate with Spise.
Or you could use EDAs,like Simplis.

create the equvient model for SC circuit
