Document Type and Number:
WIPO Patent Application WO/2015/004863
Kind Code:
A1
Abstract:
A switched capacitor circuit (200) is provided with: a capacitor (211), which has a first terminal and a second terminal, and which is disposed such that an input voltage is applied to the first terminal; an inverting amplifier (221) having a second input terminal thereof connected to the second terminal; a capacitor (231), which has a third terminal, a fourth terminal, and a fifth terminal, and has the fifth terminal connected to an output terminal (208); a capacitor (241), which has a sixth terminal, a seventh terminal, and an eighth terminal, and which has the eighth terminal connected to the third terminal, and the six terminal connected to a second output terminal; a capacitor (251) connected in series between the second terminal and the output terminal (208); and an offset compensating section (206) that outputs an offset voltage to the fourth terminal and the seventh terminal, said offset voltage having a short-circuit voltage value of the inverting amplifier (221).
