Abstract
A sample-and-hold circuit has an impedance converter, a first switch, an amplifier, an input circuit for receiving an input signal and supplying an output signal corresponding to the input signal to the amplifier, through the impedance converter and the first switching means, output-holding capacitor coupled between the input and output terminals of the amplifier, and a feedback circuit coupled between the output terminal of the amplifier and the input terminal of the impedance converter. The input circuit and the feedback circuit are a first switched capacitor and a second switched capacitor, respectively.
