Two popular ways of measuring the loop gain T of a negative-feedback circuit are Middlebrook’s double-injection method [1] and Rosenstark’s open-circuit/short ...

A new study examines the circulation in the eastern Gulf of Mexico and sheds new light on the behavior of the Loop Current and Loop Current Eddies, the relation between the upper- and lower-layer ...

Observations on nodal and loop analysis that can save a fair amount of scribbling of equations when using Kirchhoff's laws. In a previous Idea for Design, Anshi Chen outlined a method for analyzing ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices ...

Researchers have proposed a new way to control power factor correction circuits that could lead to sensorless power control.

Use of 4-to-20-mA current loops involves more than just a simple series connection between sensor, display, and power supply. The point where a sensor takes a measurement is, at times, many yards away ...

This application note’s primary goal is to provide an easy-to-understand primer for users who are not familiar with 4-20mA current-loops and their applications. Some of the many topics discussed ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...
