An image sensor may include a comparator including a first input terminal configured to receive a reset signal, a second input terminal configured to receive an image signal, a third input terminal configured to receive a ramp signal configured to ramp in one direction, and an output terminal. The comparator may further include a switch circuit including a plurality of switches. The comparator may be configured to compare the reset signal with the ramp signal and output a first comparison signal through the output terminal according to a first arrangement of the switches in a reset phase and the comparator may be configured to compare the image signal with the ramp signal and output a second comparison signal through the output terminal according to a second arrangement of the switches in an image phase.

An analog-to-digital conversion circuit includes a plurality of comparators and an averaging circuit. The averaging circuit is configured so that a length of a metal routing connected between output terminals of two comparators arranged on a leftmost side from among the plurality of comparators or a length of a metal routing connected between output terminals of two comparators arranged on a rightmost side from among the plurality of comparators is less than a length of a metal routing connected between output terminals of two comparators to which reference voltages having levels that are closest in magnitude are input.

Analog-to-digital conversion circuit

An analog-to-digital converter includes a first logic unit and a second logic unit. The first logic unit is configured to receive a plurality of thermometer codes and inverse thermometer codes generated based on an analog signal received by the analog-to-digital converter and to generate a plurality of first digital codes that periodically repeat the same pattern based on a transition position of a logic value in each of the thermometer codes and the inverse thermometer codes. The second logic unit is configured to receive the plurality of first digital codes and to generate a plurality of second digital codes based on logic values of a plurality of bits among all bits of each of the first digital codes.
