It may come as a surprise to some that a control loop’s Bode plot does not always depict the loop stability and that the output impedance measurement, obtained non-invasively, always does. Challengers ...

An editor of a technical magazine once told me that subject matter recirculates every eight months as a method of informing an ever-changing audience. It’s been a while since I addressed Bode plots as ...

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 ...

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 ...
