Noise is a fact of life, especially in electronic circuits. But on our paper schematics and just as often our simulations, there is no noise. If you are blinking an LED on a breadboard, you probably ...

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 ...

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 ...

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 ...

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 ...
