Abstract
A method for measuring a magnetic field via a Hall cross (12) including two orthogonal branches (120, 122), in which, for a given state of the Hall cross, a polarization current is made to flow in one of the branches of the Hall cross, referred to as the “polarization branch”, and a voltage is measured in the other branch, referred to as the “measurement branch”, the measured voltage including a useful signal representing the magnetic field, the method including the modulation of the useful signal via a switching sequence consisting in placing the Hall cross in Nb successive states, and the demodulation of the useful signal. The switching sequence is furthermore chosen in such a way that a measurement bias and interference pulses are zero-mean after demodulation. A switching Hall-effect sensor (10) is also described.
