Feedback is an ubiquitous and unavoidable basic technique that keeps the world running. It is only controversial in consumer audio, and then only specifically in power amplifiers. This dates from ...

Although current-feedback operational amplifiers (op amps) have been on the market since the 1990s, the current-feedback fully differential amplifier was not introduced until 2007. There are several ...

As Axiom’s chief R&D engineer Tom Cumberland describes it, a digital amplifier is a “power DAC”, and of course a DAC (Digital-to-Analog Converter) is the basis of all digitally recorded media, whether ...

Download this article in .PDF format This file type includes high resolution graphics and schematics. Feedback systems have a wide range of applications including different types of amplifiers, signal ...

THE use of negative feedback to give improved performance in a number of important respects is now a well-established feature of amplifier design technique, and the simple mathematical treatment of an ...

Probably no single issue faces more high-speed signal path designers (and supplier support teams) than the risk of instability in higher speed op amps and fully differential amplifiers (FDA). Some ...
