Claim 3:
4. The analog-to-digital converter of claim 1, wherein the first out signal comprises an output signal (out+) and an output signal (out−) that are mutually inverted,
wherein the second intermediate signal comprises an intermediate signal (in2+) and an intermediate signal (in2−) that are mutually inverted,
wherein the reference signal comprises a first reference voltage and a second reference voltage that are mutually inverted, and
wherein the second input unit, comprises:
a plurality of first switches each having one end connected to a terminal to which the first reference voltage is applied and configured to be turned on and off in response to the second output signal;
a plurality of second switches each having one end connected to a terminal to which the second reference voltage is applied and configured to be turned on and off in response to the second output signal;
a plurality of first capacitors having one end connected to a terminal to which output signal (out+) is input and another end connected to the plurality of first switches and the plurality of second switches, and outputting the intermediate signal (in2+);
a plurality of third switches each having one end connected to a terminal to which the first reference voltage is applied and configured to be turned on and off in response to the second output signal;
a plurality of fourth switches each having one end connected to a terminal to which the second reference voltage is applied and configured to be turned on and off in response to the second output signal; and
a plurality of second capacitors having one end connected to a terminal to which the output signal (out−) is input and another end connected to the plurality of third switches and the plurality of fourth switches, and outputting the intermediate signal (in2−).
