Abstract
An analog-to-digital conversion device includes a switch, a capacitor array, a comparator, and a logical control circuit. The switch is configured to sample at least one input signal according to a sampling signal. The capacitor array includes a plurality of capacitors. The plurality of capacitors are configured to store the at least one input signal. The comparator is configured to generate a comparing result according to the at least one input signal stored in the plurality of capacitors of the capacitor array. The logical control circuit is configured to respectively reset the plurality of capacitors according to a conversion end signal or the sampling signal.
