<P> A negative - feedback amplifier ( or feedback amplifier ) is an electronic amplifier that subtracts a fraction of its output from its input , so that negative feedback opposes the original signal . The applied negative feedback can improve its performance ( gain stability , linearity , frequency response , step response ) and reduces sensitivity to parameter variations due to manufacturing or environment . Because of these advantages , many amplifiers and control systems use negative feedback . </P>
