Abstract: 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.

Abstract: 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.

Abstract: Disclosed are a mobile communication terminal and a method capable of taking a high-quality picture by providing a flash or light function according to ambient luminance when a camera mounted in the mobile communication terminal takes a picture. The mobile communication terminal equipped with a camera includes: a luminance sensor unit for outputting an analog electrical signal proportional to ambient luminance; a control unit for generating a preview light enable signal according to the analog electrical signal; and a preview light for emitting light in a preview mode in response to the preview light enable signal.
