Let’s say that for a project you are working on, you need an op amp (of course, I would like it to be one of one of Touchstone’s op amps), and you want to make sure that the amplifier meets your ...

Looking at the amplifier circuit shown in Figure 1, one could estimate how stable it is by determining the phase shift encountered when the signal goes around the loop one time, while the loop is ...

Imagine being asked to provide sound reinforcement for a meeting that occurs in a large room, where anyone can be the speaker, and in a situation where microphones would hinder the flow of the meeting ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

Negative feedback is used in voltage regulators, point-of-load (POL) regulators, voltage references, operational amplifiers (op-amps), and other electronic circuits in order to produce an accurate ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

“The feedback is in the analogue domain, around the full-bridge power stage,” TI’s Ryan Kehr told EW. Texas Instruments has introduced what it claims is the first singe-chip digital input Class-D ...
