Is it possible to design an unconditionally stable linear voltage regulator? In fact, many believe that most regulator ICs are...

There are cases where a Bode (gain?phase) plot cannot be obtained from a control loop. For example, a three terminal regulator or hybrid...

The measurements are performed on the Picotest Voltage Regulator Test Standard (VRTS) testing board1 which comes with the regulators...

Output impedance is the key to testing filter and regulator phase margin, even when the control loop is inaccessible. Many voltage...

A number of test signal injectors are used when evaluating the performance of power supplies and other low-frequency components with a...

This application note also shows how the phase margin of a linear voltage regulator (LM317) can be measured using the Bode 100 and...

Developed to aid power supply designers in control-loop stability analysis, Picotest’s line of signal injectors are being introduced as...

Is it possible to also measure the audio susceptibility (Vout/Vin) of a power supply with the current injector J2111A? Yes.  The J2111A...

What are the main differences between J2100A injection transformer, J2110A solid state injector and the J2111A current injector? The...

Why do I need the J2111A if I already have an electronic load? The J2111A is not the same as an electronic load.  In many cases, the use...

How do I get a Bode plot with the J2111A? It is not possible to get a Bode plot using this method, only the phase margin; however it is...

I see that with the J2111A can perform the “non-invasive stability” measurement. I don’t understand what we can take away about stability...

I would like to measure output impedance using the J2111A Current Injector, but the 25mA offset is way above my typical operating...
