A Bode Plot Without Access to the Control Loop

This extreme measurement seems more impossible than difficult.  The traditional stability assessment method for voltage regulators is the Bode plot.  Access to the control loop is required and a small signal is injected into the control loop, usually via a resistor, placed at the top of the voltage sense divider. Without access to this voltage divider, there isn’t a place to inject a signal into the control loop, and therefore the Bode plot is seemingly impossible…

Now that I am teaching full time and have a number of undergraduate and graduate students doing weekly project reviews, I listen to more presentations than I give. I find myself giving the same feedback over and over again. So, I thought I would share my eight most common comments and tips to engineers giving presentations.

Validation of Bend Models with Measurements

Bends in PCB traces look like very basic, simple structures that are easy to simulate. Technically, one can do the analysis with any electromagnetic solver with sufficiently accurate port de-embedding capabilities. The reflections from a bend in fine-line, high-speed digital interconnects are relatively small and may not even be detectable with measurement. So, who cares? Read on to find out more.
