Abstract
A comparator system for comparing a level of an input signal with a level of a reference signal comprises a first comparator configured to input the input signal to one of input terminals thereof and the reference signal to the other of input terminals thereof, a second comparator configured to input the reference signal to one of input terminals thereof and the input signal to the other of input terminals thereof, and a control circuit configured to input an output of the first comparator and an output of the second comparator. The control circuit selects one of the outputs of the first and second comparators quicker in level change timing, and controls an output signal of the control circuit at the level change timing of the selected output.
