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 ...

(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 ...

Electrical engineers designing analog electronics commonly have to drive a capacitive load with an operational amplifier that cannot quite handle the required capacitance. Common approaches to ...
