ABSTRACT:
In accordance with the teachings of the present invention, a temperature dependent voltage generator circuit is provided for generating an output voltage that changes proportionally with changes in the operating temperature of the temperature dependent voltage generator circuit. The temperature dependent voltage generator circuit includes binary weighted current sources and electronic switches that are selectively closed in order to produce a binary weighted current. The binary weighted current is adjustable such that the output voltage of the temperature dependent voltage generator circuit may be "nulled" or forced to zero at any given operating temperature.
