The present invention relates to a feedback amplifier including: an amplification unit for amplifying an input signal, input from an input terminal, and outputting the input signal to an output terminal; a feedback circuit unit, arranged between the input terminal and the output terminal, for applying a feedback resistance value to a signal, output through the output terminal, and adjusting a gain of the amplification circuit unit by adjusting the input signal by bias voltage applied after the feedback resistance value is determined; a bias circuit unit for generating the bias voltage; a packet signal sensing unit for generating a fixed resistance control signal for controlling a fixed resistance value, included in the feedback resistance value, through comparison between output from the output terminal and a minimum signal level; and a fixed resistance control unit for controlling the fixed resistance value, included in the feedback resistance value, in response to the fixed resistance ...
