Abstract
Provided herein is a feedback amplifier including an amplifier circuit configured to amplify an input signal input from an input terminal and output the amplified input signal to an output terminal; a feedback circuit configured to apply a feedback resistance value to a signal output to the output terminal, and to control a gain of the amplifier circuit by adjusting the input signal by a bias voltage applied with a feedback resistance value determined; a packet signal sensor configured to generate a fixed resistance control signal for controlling a fixed resistance value included in the feedback resistance value through a comparison between the output from the output terminal with a minimum signal level; and a fixed resistance controller configured to control the fixed resistance value included in the feedback resistance value in response to the fixed resistance control signal.
