AN INFRARED DETECTING CIRCUIT AND AN INFRARED DETECTOR
摘要
An infrared detecting circuit is provided with a current-to-voltage converting circuit including a capacitor connected with an inverting input terminal and an output terminal of an operational amplifier and a resistance circuit element connected in parallel with the capacitor, an inverting amplifying circuit connected with an output side of the current-to-voltage converting circuit, a band-pass filter circuit connected with an output side of the voltage amplifying circuit, and an output circuit connected with an output side of the band-pass filter circuit. The infrared detecting circuit and an infrared detector including this circuit can be miniaturized.
