Abstract:
A switched capacitor circuit includes a capacitor and switches located on an input side and an output side of the capacitor. The switched capacitor circuit also includes an operational amplifier of a later stage which receives an output of the capacitor, wherein a current value of a current supplied to the operational amplifier is switched according to at least one open/closed state of at least one of the switches.
