摘要： Disclosed is an analog-to-digital conversion device. The analog-to-digital conversion device includes a signal generating unit that generates a plurality of comparison voltages based on an analog input voltage and generates a plurality of comparison results of the plurality of comparison voltages based on a sampling period, a calculation unit that skips a comparison result generated by a comparison voltage having a smallest difference between the analog input voltages among the plurality of comparison voltages from the plurality of comparison results and generates an end of comparison based on a remaining plurality of comparison results, and a SAR logic unit that generates a digital signal corresponding to the end of comparison and stores information for each bit of the digital signal.
