Optical receiver
专利汇可以提供Optical receiver专利检索，专利查询，专利分析的服务。并且PURPOSE:To deliver the output obtained by the optical signals ranging from a DC through a high frequency without using any capacitor or variable resistance, by biasing a pair of photodetecting elements with the same power supply and comparing the voltages between both ends of the load resistance after making the optical signal incident to one of the two photodetecting elements. CONSTITUTION:The photodetecting elements using PIN photodiodes 2a and 2b are biased with the same power supply 1, and the optical signal sent from an optical fiber 7 is made incident to the diode 2a of one side. The load resistances 3a and 3b are connected to the diodes 2a and 2b respectively, and the terminal voltages of the resistances 3a and 3b are applied to the input terminal of an operational amplifier 6 via resistances 9a and 9b respectively. The DC voltage obtained by the adverse bias voltage of the diodes 2a and 2b is eliminated by the amplifier 6. Then the current flowing to the resistance 3a is converted into the voltage and then delivered from the amplifier 6. Thus the output voltage corresponding to the optical signals ranging from a DC through a high frequency is delivered.，下面是Optical receiver专利的具体信息内容。
