    摘要: Provided is a feedback amplifier. The feedback amplifier includes: an amplification circuit unit amplifying a bust packet signal inputted from an input terminal and outputting the amplified voltage to an output terminal; a feedback circuit unit disposed between the input terminal and the output terminal and controlling whether to apply a fixed resistance value to a signal outputted to the output terminal; a packet signal detection unit detecting a peak value of a bust packet signal from the output terminal and controlling whether to apply the fixed resistance value; and a bias circuit unit generating a bias voltage, wherein the feedback circuit unit determines a feedback resistance value to change the fixed resistance value in response to at least one control signal and adjusts a gain by receiving the bias voltage.
