Hi All,
I am trying to simulate the frequency response of a switched capacitor amplifier. For this, I have replaced the dynamic CMFB of the opamp by an ideal continuous-time one and I have frozen the clocks to amplification mode (that is, now the amplifier has the capacitive divider feedback around the opmap). And I am biasing the input nodes of the opamp to the right common mode through BIG inductors.
With this configuration, if I run .OP, the simulation shows convergence error. I need some help to fix this. Is there any fundamental issue with respect to such a setup to characterize the switched-capacitor circuits?
Thanks & Regards Rajesh
