Abstract
A method includes alternately coupling a selected one of a plurality of current sources and two or more of the plurality of current sources to a first terminal of a bipolar device during first and second phases of a modulator cycle of a plurality of modulator cycles. The method further includes providing sampled voltages from the first terminal of the bipolar device to a modulator to produce a modulator output signal, filtering the modulator output signal to produce a filtered output signal using a back-end filter having an impulse response, and determining a temperature in response to the filtered output signal.
