摘要：
A comparator includes a first inverter which is inserted between a power source terminal and one end of a first variable resistor, includes a first FinFET provided with a first gate terminal for receiving a positive phase output signal, and a second gate terminal for receiving a clock signal changing between a first level and a second level, inverts the positive phase output signal, and outputs a negative phase output signal, and a second inverter which is inserted between the power source terminal and one end of a second variable resistor, includes a second FinFET provided with a third gate terminal for receiving the negative phase output signal, a fourth gate terminal for receiving the clock signal, and the same polarity as the first FinFET, inverts the negative phase output signal, and outputs the positive phase output signal.
