Classification: CPC G  H | IPC G  H

Claim 4:
5. The signal detection circuit according to claim 3, wherein
the detection circuit includes:
an amplifier that receives, as input signals, the signal from the second terminal of the first capacitor and the signal from the second terminal of the third capacitor, the amplifier amplifying the input signals and outputting the amplified signals as output signals;
a comparator receiving the output signals output from the amplifier;
an identical signal input unit that inputs identical signals to input terminals of the amplifier;
a storage capacitor having a first terminal connected with an output terminal of the amplifier and a second terminal connected with an input terminal of the comparator; and
a switch connecting the second terminal of the storage capacitor to the predetermined reference potential.
