とする光受信回路。 In an optical receiving circuit that converts an optical signal into an electrical signal by connecting a first transistor with a grounded emitter to a second transistor with a common collector and applying feedback to the light receiving element, the emitter is grounded. By connecting the collector of a third transistor whose base is connected to the emitter of the first transistor constituting the amplifier circuit to the input terminal of the amplifier circuit, external noise optical components generated in the light receiving element are removed. An optical receiving circuit characterized in that it is configured as follows.
