Abstract

A method of reading out a Hall plate which comprises at least 4 contacts. The method comprises: reading out two of the contacts while biasing two other contacts of the at least 4 contacts thereby obtaining a readout signal; switching biasing and readout contacts according to a random or pseudo-random sequence of phases, each phase corresponding with a different permutation of biasing and readout contacts selected from the at least 4 contacts of the Hall plate wherein the biasing and readout contacts are selected such that the readout signal is a measure for the magnetic field; processing of the readout signal to obtain a readout of the Hall plate representative for the magnetic field.
