    • This photodetecting circuit 1 is capable of suppressing oscillation of an output, and operates as a zero bias circuit in a case of a small photoelectric current to an extent that a dark current is concerned about, and limits an output current in a case of a large photoelectric current to an extent that troubles are caused in the circuit operation. Because a resistive element TR2 is provided in the photodetecting circuit 1, even when a modulation frequency of light, in other words, a frequency of a photoelectric current I flowing in a photodiode PD is made higher, oscillation can be suppressed. Further, due to the resistive element TR2 being inserted, this functions as a limiter as well, and a bias voltage to be applied to the photodiode PD is made to be a positive bias voltage, which prevents an excess current from being generated to suppress abnormal operations of the circuit.
    • 该光检测电路1能够抑制输出的振荡,并且在小的光电流的情况下作为零偏置电路工作到一个暗电流的程度,并且在大的情况下限制输出电流 光电流在电路操作中引起故障的程度。 由于在光检测电路1中设置有电阻元件TR2,所以即使光调制频率,即光电二极管PD中流过的光电流I的频率高,也能抑制振荡。 此外,由于电阻元件TR2被插入,所以这也用作限制器,并且要施加到光电二极管PD的偏置电压被设为正偏压,这防止产生过电流以抑制异常 电路操作。
