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 ...

As the use of microcontrollers, CPUs and FPGAs continues to grow, more engineers are facing challenges with their power distribution network (PDN) design. Many engineers are just starting to perform ...

The collection of test instruments in the Multisim SPICE version that I've been using does not include an impedance measurement tool. However, one can make such a tool using the Bode analyzer, an AC ...
