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 ...

This article describes how Bode plots can be used as a tool to quickly assess if your power supply design will meet the requirements for dynamic control behaviour. Power supplies normally maintain a ...

Since the inception of electronic communications, frequency response has been the common measurement unit for most instruments. Even after the introduction of the feedback amplifier, frequency ...

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 ...

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 ...
