please the pic below:
why the chop amp has a large spike when the output is unstable?
and the output drop to a lower voltage and with large offset when the op is switching after 100us?
the simulation condition is
vin+ => fixed voltage input
vin- => connect to the output R divider.
loading is 60K resistor with a 40p cap..
the non-overlap clock generate after 100us for double check the effect with and without chopper .
