Abstract:
1. A magnetoresistive angle sensor comprising: a first plurality of conductors arranged in parallel with one another in a first plane to form a first array; a second plurality of conductors arranged in parallel with one another in a second plane to form a second array, the second plane being different from and spaced apart from the first plane, and the second plurality of conductors being orthogonally arranged with respect to the first plurality of conductors; and at least one magnetoresistive element disposed proximate both the first plane and the second plane; and sensor circuitry configured to measure a first angle of an applied magnetic field sensed by the at least one magnetoresistive element with no current in the first or second pluralities of conductors and measure a second angle of an applied magnetic field sensed by the at least one magnetoresistive element with current applied to the first and second pluralities of conductors.
