hi all~ Now I use Pnoise & PSS to simulate chopper noise analysis. And I use one stage fully-difficential OP and four switches to modulate noise at output of OP without C-load at switches outputs. but with PNOISE analysis I can not see the flicker noise at chopper frequency, the flicker noise is also there just lower than before choppered. could anyone help me how to use it?
