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 ...

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 ...

Bode plots – or frequency response graphs – are found in just about every piece of literature for high-end audio equipment. It’s a simple idea, graphing frequency over amplitude, but making one of ...

(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 ...
