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, … ...

Putting this method into practice, the Bode plot is extracted from an LM317 regulator with a 100uF tantalum output capacitor, operating at 25mA load current.

The Bode plot includes markers for the gain and phase at both the 658Hz crossover frequency and also at the ringing frequency of 850Hz. Why are the various measurements in disagreement?

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 ...
