WebInput and output impedances of a negative-feedback amplifier (closed-loop amplifier) become sensitive to the gain of an amplifier without feedback (open-loop amplifier)—that exposes these impedances to variations in the open-loop gain, for example, due to parameter variations or nonlinearity of the open-loop gain. WebNov 13, 2015 · Thus, this feedback-based noise-reduction technique is essentially a way of using the superior noise performance of low-power amplifiers to reduce the effects of noise introduced by a high-power amplifier. So here is the new circuit model: Recall our formula for the closed-loop gain of a negative-feedback amplifier: GCL = A 1+Aβ G C L = A 1 + A β
