    • An object of the present invention is to provide an optical receiving circuit that it is possible to even a gain during a broad frequency band. The optical receiving circuit according to the present invention comprises an amplifier for feeding back negatively and amplifying an input signal, and a reflection coefficient setting circuit for setting an input reflection coefficient of the amplifier. For example, the reflection coefficient setting circuit has a resister Rin. One end of the resistor Rin is connected to an input terminal of the amplifier, and the other end of the resistor Rin is supplied with a voltage Vin substantially equal to a direct-current component of an input signal IN. The resistance of the resistor Rin is set so that the input reflection efficient becomes about less than about 0.3. Therefore, a peaking does not occur even at a resonance point, and it is possible to even a gain during a broad frequency band.
    • 本发明的目的是提供一种光接收电路,其可以在宽频带内甚至获得增益。 根据本发明的光接收电路包括用于反向反馈并放大输入信号的放大器和用于设置放大器的输入反射系数的反射系数设置电路。 例如,反射系数设定电路具有电阻Rin。 电阻器Rin的一端连接到放大器的输入端子,并且电阻器Rin的另一端被提供有基本上等于输入信号IN的直流分量的电压Vin。 设置电阻Rin的电阻使得输入反射效率变为约小于约0.3。 因此,即使在共振点也不发生峰化,并且在宽频带内甚至可以获得增益。
