Because I can't use spectre,I need to simulate the stability of sc_cmfb circuit using hspice.
I break the cmfb point and add the equivalent load at the output of the cmfb, then using the dc point with cmfb to doing ac analysis to see the phase margin.I'm not sure whether the method is right. Can anyone give me some suggestion? Thank you very much.
