Provided is a feedback amplifier including: an amplification circuit unit to generate an output voltage by amplifying an input voltage inputted through an input terminal; an output circuit unit to output the generated output voltage through an output terminal; a feedback circuit unit to control the gain of the amplification circuit unit by determining a total feedback resistance value using an external control signal and controlling an input current while the total feedback resistance value is determined; and a bias circuit unit to apply a bias voltage to the feedback circuit unit.
