Provided is a light receiving circuit, comprising four operational amplifiers, eight coupling resistors, an output triode, an auxiliary triode and a photodiode which are connected according to the scheme to respectively form a main line and an auxiliary line, wherein the main line is used for controlling the turn-on / turn-off of triodes; the auxiliary line is used for rapidly discharging the charge stored on the base electrode of the output triode. The invention provides a new light receiving circuit which has the performance of low transmission time delay; meanwhile, the light receiving circuit can reduce the delay difference between two voltage control signals through a second anti-phase amplifier, thereby optimizing output waveforms of the light receiving circuit.
