Patent ID: 8102175

Claim:
A magnetic field sensor device, comprising: at least two magneto-resistive sensor elements; and a switch which is adapted to have a first and a second switching configuration and which is connected to a first and a second magneto-resistive sensor element of the at least two magneto-resistive sensor elements for electrically connecting, in the first switching configuration, the first magneto-resistive sensor element to a magnetic field detection arrangement, and for electrically connecting, in the second switching configuration, the second magneto-resistive sensor element to the magnetic field detection arrangement, wherein the magnetic field detection arrangement is formed to provide an output signal based on a magnetic field currently applied thereto; a non-volatile memory formed to store information regarding a measurement characteristic of the magnetic field detection arrangement during the first or second switching configuration; and a control circuit coupled to the non-volatile memory and formed to control the switch for selectively coupling the first or second magneto-resistive sensor element to the magnetic field detection arrangement in accordance with the stored information.
