I make the figure using cmdmprobe clear.
hello raja.cedit, you said "For a +ve feedback ckt, -ve GM margin make sense,but it didn't understand what is the use with finding GM." what is the meaning +ve feedback ckt? I need finding GM because I want to make sure the circuit can oscillate.
Hello rfidea, this circuit is a differential circuit, but when using iprobe, all the feedback loop is broken, so I think iprobe should be used, but I am not very sure.
