ABSTRACT:
A device includes a pair of individual sensors spaced apart from each other. A current source provides current to both of the individual sensors. A differential temperature sensor is coupled thermally proximate the individual sensors and provides a temperature difference signal that is combined with current from the current source to provide a correction factor for a temperature gradient across the individual sensors. Alternatively, temperature responsive excitation sources may be positioned thermally proximate the sensors to provide temperature compensation.
