Claim 4:
5. The analog-to-digital converter of claim 1, wherein the first intermediate signal comprises an intermediate signal (in1+) and an intermediate signal (in1−) 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 first output signal comprises an output signal (out+) and an output signal (out−) that are mutually inverted,
wherein the amplification unit comprises:
an amplifier comprising a first input terminal to which the intermediate signal (in1+) is input, a second input terminal to which the intermediate signal (in1−) is input, a third input terminal to which the intermediate signal (in2+) is input, a fourth input terminal to which the intermediate signal is input (in2−), a first output terminal to which the output signal (out+) is output, and a second output terminal to which the output signal (out−) is output;
a first capacitor and a first switch that are connected in series between the first input terminal and the first output terminal;
a second capacitor and a second switch that are connected in series between the second input terminal and the second output terminal;
a third capacitor and a third switch that are connected in series between the third input terminal and the first output terminal; and
a fourth capacitor and a fourth switch that are connected in series between the fourth input terminal and the second output terminal, and
wherein the first switch and the second switch are turned on in odd numbered time periods and turned off in even numbered time periods, and the third switch and the fourth switch are turned off in the odd numbered time periods and turned on in the even numbered time periods.
