Abstract: An analog-to-digital converter (ADC) for converting an analog signal into a digital signal includes an amplifier circuit configured to receive the analog signal, and to generate a plurality of amplifier signals by amplifying the analog signal; a comparison circuit configured to compare a plurality of voltage levels corresponding to the plurality of amplifier signals with a positive reference voltage level and a negative reference voltage level, and to output conversion target signals based on a result of the comparison; and a converter circuit configured to convert the conversion target signals into a plurality of digital signals.
