Abstract
A localized substrate heater is configured to apply variable substrate heating to an integrated bipolar transistor. The base-to-emitter voltage (Vbe) of that bipolar transistor at varying substrate temperature settings is sensed, with the sensed Vbe processed to determine temperature coefficients of the bipolar transistor. The bipolar transistor may, for example, be a circuit component of an integrated temperature sensing circuit.
