Abstract
A voltage detection circuit for comparing an input voltage against a reference voltage, the reference voltage being derived from the threshold voltage of a semiconductor active device which forms a portion of the voltage detection circuit. To make the detection circuit substantially independent of ambient temperature changes, it is constructed as an integrated circuit and includes devices for producing a temperature dependent voltage equal to but of opposite sign to the temperature sensitive voltage component of the reference voltage. The two temperature sensitive voltages cancel each other to thereby permit a temperature independent voltage comparison.
