Abstract
A comparator circuit can achieve a reduction in current consumption with a simple configuration, and can suppress an increase in current consumption accompanying a rise in power source voltage. A current mirror circuit is connected to a power source, and gates of MOSFETs of the circuit are interconnected. An input signal is applied to a gate of an NMOSFET of the circuit. By determining the value of the signal with a constant voltage device, the voltage across a tail resistor is constant, even in the event that the power source voltage and the input signal change.
