Abstract
A reference voltage device that consists of a series combination of reverse biased p-n junctions, forward biased p-n junctions, and Schottky hot carrier diodes. The relatively low voltage and low negative temperature coefficient of Schottky diodes permit great flexibility in correcting areas of nonlinearity in the offsetting temperature dependent characteristics of conventional forward biased junctions and zener diodes. Because of the stability of Schottky hot carrier diodes to radiation, the method and apparatus of this invention are particularly suitable for designing radiation hardened reference diodes, as well. Finally, the Schottky forward biased diode is suitable for integration into a single monolithic chip structure in series with conventional reverse and forward biased p-n junctions.
