What could be simpler than inductors? Pick one from a catalog based on saturation, inductance, DCR, etc, and you’re done. If you need...

This video focuses on single-port measurements, describing how they can be applied to low power circuits such as linear regulators,...

Here is a typical noise plot showing the typical noise is 2.4nV/rt_Hz when using the J2180A Ultra Low Noise Preamp. #faq #j2180a #noise...

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

In this 5-minute video presentation, Steve Sandler discusses how stability impacts circuit performance, offering examples that...

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

Our J2112A current injector has been the most requested product to date.  It provides a very fast low current pulse, though based on a RF...

Assuming the AC signals in the measurement are very small, the power ratings of the ports limit the absolute maximum DC voltage that can...

Clock-jitter performance has become a top priority among clock, analog-to-digital controller (ADC), and power-supply manufacturers. Why?...

Evaluating the stability of a Point-Of-Load (“POL”) regulator can be performed using both traditional Bode plot and output impedance...

We can equate the stability to an equivalent phase margin by assuming the magnitude of the gain vector to be 1 and solving for the Q. In...

High Fidelity POL Testing with the J2112A The J2112A: Faster, Non-Invasive, and High Fidelity POL Step Load Testing Testing the step load...

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

Making ripple measurements has traditionally been using an oscilloscope. For a number of technical reasons, an oscilloscope, in general,...

Wherever you find a digital control signal, you find sharp rising and falling edges that need characterization. These edges occur on...

Summary Among the most frequently asked questions regarding non-invasive stability measurement are “How do I determine the bandwidth,...

Oscilloscopes often are used to measure power supply, linear regulator, and reference noise. Since an oscilloscope has a sensitivity in...

Using a simple, but precise test set up, measurements are taken on a 1-m? 5% metal-foil current-sense resistor mounted to a small PCB....

The general industry trend is to make electronic products more efficient and, in general, consume less energy. One of the major...
