Abstract:
In some embodiments, a position sensor calibration and linearization system for position sensors is provided. A method of calibrating and linearization of a position sensor includes reading Spatial Angle data from a position sensor at a set of positions of a target swept over receive coils in the position sensor; calculating calibration parameters from the Spatial Angle data; determining an initial position values from the Spatial Angle data and the calibration parameters; determining linearization parameters from the initial position values; and writing the calibration parameters and the linearization parameters into the position sensor.
