Pspice phase margin
WebTo use the SPICE method, set ACOUT=0. The SPICE method is typically used to calculate the nodal vector difference in comparing adjacent nodes in a circuit. It is used to find phase or magnitude across a capacitor, inductor, or semiconductor device. WebYou really want a phase margin > 35 degrees. We'll go through steps 1 and 2 using your loop as example. 1. Quick and Dirty Red Flags Take a quick global look at the loop for anything that stands out. In this case we see OA2, uncompensated with uncontrolled gain. Having an uncompensated amp in the loop is always questionable, and usually a bad idea.
