Hello Raghu

I looked at your schematic once again and recognized it is a single ended output structure. Is that correct? Also it is not clear which of the nodes is out? It looks to me as if 2 nodes are labelled out. Not sure if I am reading it right.

Hi ULPAnalog

Yes It is single ended output structure. both label are not same one are "out" and another one is "out-" . I tried both the cases first I given the single output of amp to anti-chopper circuit not getting result so I also tried that double ended output to anti-chopper circuit then also I am not getting result.

Thanks & Regards
Raghu

Hello

Could you post the resulting plots and key specs including the chopping frequency etc?
