摘要： A comparator is provided, which compares an input voltage and a reference voltage by using a plurality of inverting circuits connected in series. The comparator includes a first inverting circuit, a second inverting circuit, a feedback path, and a capacitor arranged on the feedback path. The first inverting circuit inverts a difference between the input voltage and the reference voltage for output. The second inverting circuit further inverts the output of the first inverting circuit for output. The feedback path feeds back the output of the second inverting circuit to the input side of the first inverting circuit. The capacitor causes hysteresis such that an increasing threshold and a decreasing threshold of the second inverting circuit corresponding to an increase and a decrease of the input voltage have a difference therebetween.
