Abstract

This work introduces a novel hybrid algorithm, which allows computing the absolute temperature of a bipolar transistor device in thermal equilibrium for sensing ambient temperature. The proposed idea relies on the measured current-voltage characteristics of the device and it can be implemented in any computing platform. Experimental data obtained, using a broad collection of commercial devices, demonstrates the accuracy of the proposed algorithm.
