Abstract
In contrast to the widespread myth that positive feedback or even unstable, open-loop amplifiers will produce unstable feedback amplifiers, it is shown that positive feedback amplifiers, can be used for realizing stable and useful feedback amplifiers. The benefits of using positive feedback for DC gain enhancement without compromising the settling time or the frequency response of feedback amplifiers are discussed
