About Negative Feedback Amplifier
What is Negative feedback amplifier?

Answer 1

    Negative feedback amplifier is an amplifier for voltage at the output.  It enhances the stability of an amplifier and nullifies any deviations from the rated output.  It provides a stable output.

   A feedback circuit is connected between the output and the input with a small multiplier.  The feedback is subtracted from the input signal , and fed to the system.

   If the output signal is more than the desired / rated value, then the negative feedback will enable the input to reduce and hence the output signal to return back to the specified/rated value.
