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 ...

How to read Bode plots to assess dynamic control behavior of a power-supply design. Observing Bode plots from an example voltage regulator to observe control-loop speed and stability. This article ...

Many applications in test and measurement take advantage of feedback to improve some aspect of performance. In simple power-sourcing instruments, for example, you can use the fact that, given the ...
