Has anyone played around with Nyquist plots as an alternative approach to feedback analysis? You have to do a bit of intervention on the axis scaling, but you can get an alternative view on an amplifiers stability using this approach. There is a nice set of articles incl. use of LTSpice (5 parts IIRC) about this here https://www.allaboutcircuits.com/te...t-1-general-structure-and-essential-concepts/
I had some reservations about the stability margins on a design I am working on using Bode plots, but using Nyquist plots the issue id crystal clear. YMMV.
