Abstract
Two Silicon Carbide negative positive negative transistors realized on a monolithic substrate as a differential pair to keep their base-emitter junctions at nearly the same temperature such that their kT/q sensitivities tract together with their base connections electrically connected to the cold junction terminals of a thermocouple to create an amplified differential voltage across output load resistors while operating at high temperature.
