摘要：
Two LPFs are disposed on the output side of a differential amplifier to remove an AC component contained in an output signal output from a first output terminal of the differential amplifier and an AC component contained in an output signal output from a second output terminal of the differential amplifier. The lowpass filter voltage of the output signal output from the first output terminal with the AC component removed is input to one of input terminals of one of two comparators, and the lowpass filter voltage of the output signal output from the second output terminal with the AC component removed is input to one of input terminals of the other comparator.
