Abstract:
Sampling capacitors are connected respectively to a pair of differential input terminals of an operational amplifier. The sampling capacitors sample input signals. Source terminals and drain terminals of dummy switches are connected respectively to paths connecting the operational amplifier and the sampling capacitors, so that a common-mode voltage of differential input voltages to the operational amplifier is adjusted by gate-channel capacitances.
