Abstract
A method for providing offset compensation in a Hall sensor comprising at least one Hall element having a plate-shaped sensor element made of a doped semiconductor material, comprises using measurements on the Hall element itself. The method comprises obtaining a first readout signal (V) from the at least one Hall element which is substantially dependent on the magnetic field, obtaining a second readout signal (V) from the at least one Hall element which is substantially independent of the magnetic field, and using the second readout signal (V) for obtaining a prediction ({circumflex over (V)}) of the offset (V) on the first readout signal (V).
