Abstract: An infrared receiving apparatus and a method thereof are provided to filter the disturbing light of a bandwidth by using an HPF having a pole frequency higher than the bandwidth, and remove signal distortion caused by excessive settling through a reset process by using the waveform characteristic of a received signal, thereby improving a noise characteristic by the disturbing light having a frequency in the bandwidth. A light receiving unit(200) receives infrared signals and provides a voltage signal. An HPF(High Pass Filter) unit(210) filters the signals provided through the light receiving unit in a pole frequency higher than an infrared signal bandwidth. An amplification unit(220) amplifies the output of the HPF unit. A waveform shaping unit(230) shapes the output of the amplification unit on the basis of a reference threshold voltage to provide a square wave. A reset unit determines the output of the amplification unit on the basis of the reference threshold voltage to reset the output of the HPF unit.
