Abstract
A temperature sensor circuit that includes two banks of bipolar transistors where the bipolar transistors of each bank are coupled in parallel in a current leg of the sensor circuit. The current legs are configured to produce voltages and currents that are dependent upon the temperature sensitivity of the bipolar transistors in the current legs. The sensor circuit includes a controller that, in some embodiments, periodically enables subsets of the bipolar transistors of each of bank during operation.
