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 ...

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 ...

Closed-loop control systems are sometimes shipped from the factory with resonances and other operational difficulties that aren't supposed to be part of the package and are not well understood.

Electrical engineers will recognize the Bode plot as a plot of the frequency response of a system. It displays the frequency on the x-axis and the phase (in degrees) or magnitude (in dB) on the y-axis ...

Oscilloscopes are the primary measurement tools used today by engineers to test and characterize their power supply designs. The R&S®RTx-K36 frequency response analysis (Bode plot) option provides a ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) AC parameters which describe the amplifier's performance over frequency can appear very ...
