Abstract
A sensor system included in an integrated circuit includes multiple sensor circuits and a control circuit. Using characterization data, a model may be generated that defines a relationship between measurable parameters of the integrated circuit and an operating characteristic of the integrated circuit. The control circuit can combine, using a function included in the model, data from the multiple sensor circuits to determine a value of the operating characteristic that is more accurate than a sensor circuit configured to measure a single parameter of the integrated circuit that varies with the operating characteristic.
