As Sandler explains, analysis based on impedance measurements can more thoroughly assess control loop stability than Bode plot...

One of the more common design techniques for power distribution networks (PDN) is the determination of the peak impedance that will...

How do you use the Picotest injectors and the Agilent analyzer to measure output impedance and/or non-invasive step loading? For the...

While the graph of Fig. 1 seems straightforward, there are several issues that become apparent when one tries to make sense of what the...

Maintaining clean, regulated voltage requires more than a high-quality power supply. The power distribution network (PDN)—which, together...

2 Port Shunt Thru Impedance Measurement With The Bode 100 Below are a few diagrams on how to do a 2-port impedance measurement and have...

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...

Many articles and application notes describe the extraction of phase margin, using a non-invasive technique that extracts the phase...

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

In this article we examine the process of measuring a key performance characteristic, output impedance, using the Picotest J2130 DC Dias...

With ESL values typically in the range of 1 nH to 5 nH, measuring the ESL of chip capacitors is not a trivial task. At present, some...
