Steve Sandler explains what every engineer should know about ‘non-invasive’ stability assessments. The non-invasive stability assessment is a method that uses an output impedance measurement to ...

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 ...

These three analysis methods are linked together, so this section is organized by control method. In contrast to the large-signal transient response that was reviewed in part 2, we will perform ac ...
