An optical receiving device. The optical receiving device has a photodiode, transimpedance amplifier, and a feedback component. The photodiode has a first terminal coupled to a voltage source and a second terminal. When detecting an optical signal, the photodiode generates a current signal output from the second terminal. The transimpedance amplifier converts the current signal to a voltage signal and outputs the voltage. The feedback component is coupled between the first terminal and a input terminal of the transimpedance amplifier. The feedback component feeds a first voltage-changing signal, occurring in the input terminal of the transimdepance amplifier with the current signal, to the first terminal.
