Zusammenfassung:	A magnetic field sensor (120) is disclosed for providing an output signal (174) in response to an external magnetic field ( H y ). The sensor (120) comprises a primary magnetic field transducer (130) for producing a primary signal (131) in response to the external magnetic field ( H y ) and having a first magnetic field saturation characteristic; a secondary magnetic field transducer (140) for producing a secondary signal (141) in response to the external magnetic field ( H y ) and having a second magnetic field saturation characteristic. The first magnetic field saturation characteristic is different from the second magnetic field saturation characteristic. The sensor (120) is configured to use the secondary signal (140) to correct for errors in the output signal (174) arising from saturation of the primary transducer (130).
