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 ...

Control theory is a vital and standard part of engineering studies: the effectiveness of negative feedback to keep jet-fighters airborne, ferries afloat and nuclear power plants a-non-exploding has ...

Current feedback amplifiers are one of the oldest amplifier topologies around. I remember the days when Comlinear ruled the market in the 80s with their high speed offerings. Analog Devices, ...

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 ...

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 ...

Voltage-Feedback operational amplifiers (VFA op amps) allow circuit designers to swap gain for bandwidth. current-feedback op amps (CFAs) are simpler to use than VFAs, but do not offer gain-bandwidth ...
