ンパレータ回路。[Claims for Utility Model Registration] A first transistor connected between an input and an output and supplied with a reference voltage, and a second transistor connected between a signal path between the first transistor and the input and ground. The first transistor compares the voltage of the signal path based on the input signal with the reference voltage to determine the output, and the output signal drives the second transistor to control the output. A comparator circuit characterized by:
