ABSTRACT:
A polynomial calculator device is applied to calibrate a sensing device. Preferably the sensing device (100) includes a sensing element (102) with an output coupled to a signal conditioning circuit (104). The signal conditioning circuit (104) is adapted to be highly computationally efficient and operable for compensating for temperature and part-to-part variation on the sensing element output for providing a useable sensor output signal. A calibration method relies on a unique polynomial calculator (118) that is implemented as part of the signal conditioning circuit (104). The sensor is preferably manufactured and packaged prior to calibration so as to avoid any post-calibration processing error. The packaged sensor is calibrated and a number of calibration values are retained in a memory (114) and accessed by the calibration method during sensing element signal processing.
