Abstract:
A switched capacitor circuit includes: a capacitor including a first terminal to which the input voltage is applied and a second terminal; an inverting amplifier including a second input terminal connected to the second terminal; a capacitor including a third terminal, a fourth terminal, and a fifth terminal which is connected to an output terminal; a capacitor including a seventh terminal, a sixth terminal connected to the second output terminal, and an eighth terminal connected to the third terminal; a capacitor connected in series between the second terminal and the output terminal; and an offset compensation unit which outputs an offset voltage having a value of a short-circuit voltage of the inverting amplifier to the fourth terminal and the seventh terminal.
