The present invention relates to an IR receiver, and more particularly, to an IR receiver that efficiently regulates a voltage gain through a control signal that varies suitably, thereby stably receiving and IR signal even when the IR signal is strongly or continuously input or when noise is excessive To an improved IR receiver structure. More particularly, the present invention relates to an IR photo diode (IR photo diode) 100 for detecting and receiving an IR signal, an AGC (Auto Gain) control circuit for controlling a voltage gain using a signal passed through the IR photo diode Controller unit 400 and an output shaper unit 500 for controlling the output of the AGC unit.
