Can spice simulate Switched-Capcitor circuit precisely?

[leohart]

I mean charge injection,clock feedthrough...etc. in SC circuit.

This normally depends on the level of SPICE you use. It should take into consideration charge injection .....

 

[mohmohcha]

to certain extend, i think yes.
but i guess it may be difficult for spice to model the charge injection.
DO ENOUGH HAND CALCULATION before you go into spice.

also, make sure your settling is correct.
if you r designing a high frequency circuit, set the tran. simulation acurracy carefully.

Yes - charge injection is notoriously hard to simulate. You're best off doing a worst-case design there...

i think it depend on the model you use, and the time will be long
