An optical receiving circuit comprises a photodetector, a differential transimpedance amplifier, a peak detector, a resistor network circuit and a discriminator. The transimpedance amplifier receives a current pulse converted by the photo-detector and outputs a non-inverting voltage signal and an inverting voltage signal of the same level. A peak detector for detecting a peak value of the non-inverting voltage signal. A resistor network circuit make an additional operations between an output signal from the peak detector and the inverted voltage signal, and between the non-inverting voltage signal and the non-inverting voltage signal, thereby generating two complemental voltage signals, which have the same amplitude and cross each other at a middle point of the amplitude. The discriminator discriminates a crossing potential at which the two complemental voltage signals generated by the resistor network circuit and generates a pulse-shaped signal with a logical level whose state is changed to another logical state at the crossing potential.
