Abstract:
A comparator circuit includes a first comparator comparing an input signal to a first comparison value and generating a first determination signal, a second comparator comparing the input signal to a second comparison value different from the first comparison value and generating a second determination signal, and an output selecting circuit selecting a signal generated first from the first determination signal and the second determination signal, and outputting the selected signal as a determination signal.
