PROBLEM TO BE SOLVED: To provide a comparator that reduces power consumption.SOLUTION: The comparator includes a first comparator for comparing an input signal with a first signal, and a second comparator for comparing the input signal with a second signal having a voltage value lower than a voltage value of the first signal if a voltage value of the input signal is lower than the voltage value of the first signal, and comparing the input signal with a third signal having a voltage value higher than the voltage value of the first signal if the voltage value of the input signal is higher than the voltage value of the first signal. |
