Claim 0:
1. A method for determining a transfer function of an angle sensor, wherein the method comprises:
generating, by the angle sensor, a sequence of angle output signals during an exposure to a rotating magnetic field;
receiving the sequence of angle output signals of the angle sensor during at least one time interval during which the angle sensor is exposed to the rotating magnetic field;
determining the transfer function of the angle sensor based on the sequence of angle output signals;
configuring the angle sensor based on the transfer function such that an angle output signal generated by the angle sensor is representative of an actual angle value;
acquiring one or more correction values from a look-up table;
using the one or more correction values to at least one of correct irregularities of the transfer function or to linearize the transfer function;
recalibrating the look-up table with an updated version of the one or more correction values, wherein the updated version of the one or more correction values is determined based on the sequence of angle output signals;
using the updated version of the one or more correction values to at least one of correct irregularities of the transfer function or to linearize the transfer function; and
generating, by the angle sensor, a corrected angle output signal based on the transfer function corresponding to the updated version of the one or more correction values.
