ABSTRACT:
A first to a fourth sampling switch (1ato1d), a first to a fourth sampling capacitance (4to7), and a first and a second charge redistribution switch (2a,2b) are provided on the input side of a differential amplifier (8). A first and a second reset switch (3a, 3b) are provided between inputs and outputs of the differential amplifier (8). A positive-polarity input signal voltage (Vinp), a negative-polarity comparison reference voltage (Vrefn), a positive-polarity comparison reference voltage (Vrefp), and a negative-polarity input signal voltage (Vinn) are applied via the first to fourth sampling switches (1ato1d) to one ends of the first to fourth sampling capacitances (4to7), respectively. During a reset period, the reset of the differential amplifier (8) is released after sampling of the voltages. During a comparison period, the first and second charge redistribution switches (2a, 2b) are caused to be in a conduction state.
