Abstract
A method reading a magnetic-field sensor provided with at least one first magnetoresistive element envisages generation of an output signal, indicative of a magnetic field, as a function of a detection signal supplied by the magnetic-field sensor. The reading method envisages: determining an offset signal present in the output signal; generating at least one compensation quantity as a function of the offset signal; and feeding back the compensation quantity at input to the reading stage so as to apply a corrective factor at input to the reading stage as a function of the compensation quantity, such as to reduce the value of the offset signal below a given threshold.
