Hi,

I am designing chopper amplifier and trying to simulate noise analysis by using PSS and PNOISE. But i am not getting any noise shift in noise plot and also not showing any noise reduction with chopping. I am using chopping frequency=20KHz and input signal frequency=1KHz. I am attaching the settings of PSS and PNOISE. Plz help me how to get proper noise plot.



Thanks
With Regards
