Consider the feedback amplifier shown in Fig. 1. What is the closed-loop transfer function of this amplifier? What is the low-frequency closed-loop gain of this amplifier? What is the bandwidth of the closed-loop transfer function? Figure 1: Feedback amplifier.

Solution

A negative feedback amplifier (or feedback amplifier) is an electronic amplifier that subtracts a fraction of its output from its input, so that negativefeedback opposes the original signa
