Jose Marcos Laraia, David John Willis: Providing nonlinear temperature compensation for sensing means by use of Padé approximant function emulators. AMI Semiconductor, MacPherson Kwok Chen & Heid, July 8, 2008: US07398173 (6 worldwide citation)

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 ...

Jose Marcos Laraia, David John Willis: Providing nonlinear temperature compensation for sensing means by use of padé approximant function emulators. Semiconductor Components, Haynes and Boone, August 2, 2011: US07991571 (5 worldwide citation)

Pade Approximant function emulators are used to model the nonlinear offset and/or nonlinear sensitivity behaviors of a sensor relative to temperature sub-ranges and to produce temperature compensating corrections for both offset and sensitivity as desired. In order to avoid use of brute force divisi ...
