Optical receiving circuit and method for manufacturing the same
An optical receiving circuit which suppresses a characteristic deterioration due to a wiring between a PD and a TIA and a method for manufacturing the optical receiving circuit are provided. A optical receiving circuit (300) comprises a photodiode (302), and a transimpedance amplifier (308) that supplies an electrical power source to the photodiode (302). The characteristic impedance of a wiring between the anode of the photodiode (302) and the transimpedance amplifier (308) is higher than the characteristic impedance of a wiring between the cathode of the photodiode (302) and the transimpedance amplifier (308).
