Filed: 1990-03-30
Abstract: PURPOSE:To expand the dynamic range of a light reception circuit by switching the load resistance of a photodetector depending whether an optical input level is high or low and switching the cut-off frequency of a high pass filter, as well. CONSTITUTION:Since a 1st reference voltage and a 2nd reference voltage are higher than the output of a peak value detection circuit 3 detecting a peak of a signal of an amplifier circuit 2 in the case of a small optical input level, a variable resistance circuit 7 gives a large resistance in a control terminal to convert the optical input of a minimum light reception level into a voltage signal. Moreover, the cut-off frequency of a high pass filter 4 with a control terminal is f1 to indicate a characteristic correcting the low gain of a high frequency. When the optical input level gets higher, the resistance of a PIN diode RC 1 is varied with a forward current. Thus, the circuit controls the variable resistance circuit 7 with a control terminal in the decreasing direction of its resistance.
