Photoelektrisches Umwandlungsmodul

摘要

It is an object of present invention to provide a low-cost photoelectric conversion module in which a signal for compensating noise caused by changes in temperature and variations in power supply is obtained. In the photoelectric conversion module according to the present invention, a first amplifier (4) having an input terminal (4a) connected to the cathode of a light-receiving element for converting an optical signal into an electrical signal amplifies the electrical signal to obtain an amplified signal. A second amplifier (6) having an input terminal (6a) connected to one electrode (5b) of a capacitor (5) outputs an amplified signal for compensating noise of the electrical signal amplified by the first amplifier. The other electrode (5a) of the capacitor is connected to the cathode of the light-receiving element. The capacitor has a capacitance value equal to the capacitance of the light-receiving element.
