ABSTRACT:
A temperature compensated differential level shift circuit is provided. An ECL type buffered differential circuit employs a source of threshold voltage, V.sub.T, which matches the temperature-dependent characteristic of the input section of the level shift circuit. In a preferred embodiment, a Schottky diode is provided in the output section of a bandgap reference voltage generator which matches the temperature dependence of a Schottky diode in the input section of the level shift circuit. As temperature shifts, the threshold voltage will shift in a manner that tracks the temperature-produced shift in the input voltage as it passes through the Schottky diode in the input section of the level shift circuit. Matched PNP or NPN transistors may also be used in the input section of the level shift circuit and in the output section of the bandgap reference voltage generator.
