Abstract
Provided is an analog-to-digital converter and a voltage offset correction method thereof. The analog-to-digital converter may include a digital-to-analog converter (DAC) configured to generate a first comparison voltage, a comparison circuit configured to output a first comparison result signal based on a result of comparing the first comparison voltage with a second comparison voltage, and a control circuit configured to control the DAC and output an output signal, wherein the DAC may include a correction circuit configured to generate a correction voltage by selectively switching switches connected to terminals to which a plurality of reference voltages are applied, and correct a voltage offset of the comparison circuit based on the correction voltage.
