Hi,

I think there is a component in the analoglib called iprobe, in order to use that , you need to put this component in between your common output from opamp and cmfb input, and run stb analysis. Hope it will help.

See http://www.designers-guide.org/Forum/YaBB.pl?num=1190707743/1#1. Connect the positive output via the cmdmprobe with the negative input and vice versa.
