摘要:
A noise reduction circuit outputs a signal corresponding to a voltage difference between two different signals. The noise reduction circuit includes: an amplifier circuit for amplifying the two different signals at different timings; and a voltage difference detection circuit for detecting a voltage difference between the two different signals amplified by the amplifier circuit. The noise reduction circuit accumulates, a predetermined number of times, an electric charge corresponding to the voltage difference detected by the voltage difference detection circuit and combines the accumulated electric charges to output a resultant electric charge.
