ABSTRACT:
An input capacitor and a plurality of reference capacitors sample an input voltage and reference voltages in a first period. A switch circuit connects the input capacitor and one of the reference capacitors between an output and an input of an amplifier in a second period. This mechanism causes a feedback gain to be “1” in the second period. Therefore, it is possible to reduce power consumption and noise.
