Does anyone know how to analyze the stability of chopper amplifier?
suppose the chopper amplifier has 3 stages.

if we just remove the chopper switch, and analyze the stability of the rest circuit, is it ok?

please help me.
Thanks.
 

for a system to become unstable the feedback should be 180 degrees... the chopper part doesnt reach this condition especially it is negative feedback...

i have not met this problem... but i'm kinda sure...
 

Bode ?i donot know
 

Maybe you can run the transisent analyis and do the ac analysis to check the stabilty by using .op time
