Abstract

PURPOSE: To solve the problems of threshold voltage and temperature compensation and perform measurement by letting the output of a constant voltage circuit be a reference value and the voltage proportional to a power source voltage be a comparing value and comparing the magnitude relation of both voltages in a differential amplifier circuit.
