It is not too often that a tool fails me. Most of the time I have made some mistake, so when a Bode Plot failed to predict an unstable system, I came down with a bad case of myopia. I spent so much ...

Many articles and application notes describe the extraction of phase margin, using a non-invasive technique that extracts the phase margin from an output impedance measurement. The term non-invasive ...
