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...
 

Can you explain in detail.Its not clear for me..
thanks

Read this paper:

Simulating Switched-Capacitor Filters with SpectreRF

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