Abstract
Sensors and/or transducers can exhibit nonlinear response to temperature changes in terms of offset and also in terms of sensitivity to variations in a sensed physical attribute (pressure, strain, displacement, etc.). Padé Approximant function emulators are used to model the nonlinear offset and/or nonlinear sensitivity behaviors of a given sensing device relative to one or more temperature sub-ranges and to produce temperature compensating corrections for offset and/or sensitivity as may be desired.
