Abstract
A comparator is provided with a pair of transistors which are continuously in ON state, in which a switch unit constructed of a diode pair, for switching a current path in response to a high/low relationship between a voltage level of an input signal and a voltage level of a reference voltage, and a unit for converting a current into a voltage level are provided between emitter terminals of the transistor pair.
