Title: Agc circuit with amplification rate
Inventor: MIWA MAKOTO
IPC: H03G3/30
Filed: 1989-02-10
Abstract: PURPOSE:To simplify a circuit and to increase the response speed by raising the bias voltage of a photodetector (APD) to set a high amplification rate at the time when the photocurrent is small by series feedback of the current path of the APD but reducing the bias voltage of the APD by the voltage drop due to a feedback resistance to reduce the amplification rate at the time when the photocurrent is large. CONSTITUTION:When the reception light level is lower, only a diode 22 is turned on because a current I is small and a bias voltage VA of an APD 1 is high, and the current I is supplied from a high voltage source VH 21, and at this time, a fixed resistance RH 26 is the feedback resistance to perform the AGC operation. That is, when the reception light level is raised and the photocurrent is increased, the bias voltage VA of the APD 1 is reduced by the voltage drop due to the feedback resistance RH 26, and as the result, the circuit is operated to reduce the amplification rate. When the reception light level is reduced, the circuit is operated to raise the amplification rate. Thus, the AGC operation is quickly performed with the simple circuit.
