The third video in the Picotest/Keysight How-To Design for Power Integrity series is now available. Power supply switching ripple and...

Capacitors are too often taken for granted. When it comes to high-speed circuits, capacitors can behave like resistors or even inductors,...

Arduino has taken the product “maker” world by storm and one of the more popular Arduino modules is the Analog Devices AD9851 DDS...

In 1938 Hendrik Wade Bode, who worked at Bell Labs, published his asymptotic assessment of phase margin and gain margin, bearing his name...

Some low-dropout regulators (LDOs) use multiple feedback loops to improve output voltage transient response. In many of these cases, some...

And by taking measurements across all three test domains, designers can trace power supply ripple-related problems back to root causes...

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

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

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

We often give even less thought to how we connect our circuits and systems to the test equipment that we use to power and measure the...

Fortunately, a new technique permits non-invasive stability testing of such devices.1 Designers can evaluate stability by measuring (on...

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

A single, simple measurement is described that allows the determination of the ESR required to achieve a desired phase margin, using a...

In this measurement the J2130A provides a DC bias to the Optocoupler LED, which returns to ground through a termination resistor. The...

RF/microwave design engineers faced with developing effective power circuits for a system require more complete data sheets, appropriate...

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...

The OMICRON Lab Bode 100 Network Analyzer, used in conjunction with the Picotest J2130A DC Bias Injector, is a perfect combination for...

Most electronic systems contain at least one voltage regulator, with many systems requiring several regulators, each providing a...
