A switched capacitor integrator is comprised of an operational amplifier, a feedback capacitor connected between the inverting input terminal and the output terminal of the amplifier, a bias circuit for applying a given voltage to the non-inverting input terminal of the amplifier, a switched capacitor, and a switch circuit which connects the switched capacitor between the signal input terminal applied with an input voltage signal and the inverting input terminal of the amplifier in a first operation mode and short-circuits the switched capacitor in a second operation mode.
