Abstract
An apparatus configured to convert an analog input signal into a digital output signal may include a first amplification circuit configured to receive the analog input signal and a plurality of reference voltages and amplify differences between the analog input signal and the plurality of reference voltages; a plurality of first capacitors configured to respectively store charges corresponding to signals outputted by the first amplification circuit; a second amplification circuit configured to amplify differences among voltages of the plurality of first capacitors; a plurality of second capacitors configured to respectively store charges corresponding to signals outputted by the second amplification circuit; and a comparison circuit configured to generate the digital output signal by comparing voltages of the plurality of second capacitors with each other.
