Title: Optical receiver
Inventor: FUKUSHIMA SHIYOUYA
IPC: H04B10/67
Filed: 1991-09-30
Abstract: PURPOSE:To attain normal operation of AGC by detecting a mean value of a drain current of a 1st stage FET, disconnecting the AGC when the said drain current exceeds a preset current so as to make a bias voltage of an APD constant. CONSTITUTION:A mean value of a drain current is detected by monitoring a potential difference across a resistor 11 by a monitor circuit 8. When the drain current exceeds a preset current by a comparator 9 and a switch 10, an AGC circuit is disconnected to control a bias voltage of an APD 3 to be constant. A gate-source level of the FET 11 is not ensured attended with the increase in an optical reception level by the operation and when the drain current increases, an output of the comparator 9 is changed and the AGC is disconnected by the switch 10. In this case, the optical reception level is returned to the normal value by setting a Vref2 so as to minimize the multiple factor of the APD 3 to restore the AGC.
