Feedback Amplifier : Effect of Negative Feedback on Amplifier Characteristics
In this video, the effect of the negative feedback on the different amplifier characteristics (gain, bandwidth, noise, gain stability) is explained through a mathematical analysis.
And at the later part of the video, one example related to that is also covered.
The following topics are covered on the video:
0:00 Introduction
1:26 Effect of negative feedback on Gain Stability of Amplifier
6:02 How negative feedback reduces non-linear distortion
9:34 How negative feedback can improve signal to noise ratio
13:51 Effect of negative feedback on the Amplifier bandwidth (Frequency Response of Feedback Amplifier)
24:20 Solved Problem
The following are the effects of the Negative Feedback on Amplifier:
1) Desensitises the Gain
2) Reduces Non-Linear Distortion
3) Reduces the effect of noise / interference (Improves signal to noise ratio under certain arrangement)
4) Increases the bandwidth of the amplifier
5) Modifies the input and output impedance of the amplifier
6) Reduces the gain of the amplifier
