Реферат: The present disclosure concerns a correction method for correcting an output signal provided by a magnetoresistive sensor in the presence of an external magnetic field, comprising: determining a deviation of the output signal from a linear response by an amplitude of a high order component signal of the output voltage; and determining a corrected output signal by compensating the output signal for the high order component signal such that the corrected output signal varies linearly with a variation of the external magnetic field within a variation range. The present disclosure further concerns an integrated circuit (IC) configured to perform the method and a characterization method to derive common parameters used when performing the correction method, for a plurality of magnetoresistive sensors.
