Abstract
Increase of power consumption is reduced, and the operational speed is improved. A comparator includes a comparing section which outputs a result of comparison between a first voltage and a second voltage which constitute an input differential signal, a first positive feedback section which operates in synchronism with a first clock signal, amplifies the result from the comparing section, and outputs the amplified result to an output node pair, and a second positive feedback section which operates in synchronism with a second clock signal, and provides positive feedback to the output node pair.
