ABSTRACT:
A precise temperature dependent voltage reference and voltage comparator comprising a three terminal circuit. When the input voltage exceeds a predetermined threshold, the output switches from the nonconducting, "off" state to a current conducting "on" state. The threshold condition can be tailored to a specific temperature characteristic and low voltage range with an input current on the order of 25 microamperes. With the output tied to the input, the circuitry can act as a reference diode.
