Title: Light receiving circuit for photoelectric switch
Inventor: IMAI SEIJI
IPC: H03K17/78
Filed: 1989-10-05
Abstract: PURPOSE:To apply a high reverse bias voltage to a photodetector irrespective of a power source voltage by providing a switching circuit which is opened at the time of light reception and an inductor. CONSTITUTION:By the output of an oscillating circuit 3, a light emitting diode 9 is driven through inverters 7, 8, and lighting is executed intermittently. When the output of the oscillating circuit 3 is in an H level, a transistor TR2 for constituting a switching circuit is conducted, and a power source si supplied through an inductor L and a resistor R2 from the power source. When the output of the oscillating circuit 3 goes to an L level, the transistor TR2 is turned off, therefore, the current of the inductor L is interrupted suddenly and counter electromotive force is generated, and the counter electromotive force is given to a photodiode 5 of the light receiving circuit 4. In such a manner, a reverse bias voltage exceeding a power supply voltage can be applied easily to the photodetector, and the saturation of the light receiving circuit caused by a DC light such as a solar light can be prevented.
