Abstract
(EN)
Disclosed is a light-quantity detecting device (1) comprising: a photoelectric conversion element (10) for converting the quantity of light inputted, into an electric current; a current-voltage converting means (100) including a positive input terminal (In+) connected with the first terminal (P-terminal) of the photoelectric conversion element, a negative input terminal (In-) connected with the second terminal (N-terminal) of the photoelectric conversion element, a negative output terminal (Out-) for reversing the polarity of an electric current inputted to the positive input terminal, to output same as a voltage, a positive output terminal (Out+) for reversing the polarity of an electric current inputted to the negative input terminal, to output same as a voltage, a first negative-feedback resistor connected between the positive input terminal and the negative output terminal, and a second negative-feedback resistor connected between the negative input terminal and the positive output terminal, thereby to zero-bias the photoelectric conversion element and to convert the converted current into a voltage; and an amplifying means (300) for amplifying the converted voltage.
