Abstract
A magnetic field sensor includes a substrate having a surface and a plurality of magnetoresistance elements supported by the surface of the substrate. Each magnetoresistance element has a respective width parallel to the surface, and each width may be a smallest dimension parallel to the surface. A first width of a first magnetoresistance element of the plurality of magnetoresistance elements may be different from a second width of a second magnetoresistance element of the plurality of magnetoresistance elements. A processing circuit may be coupled to the plurality of magnetoresistance elements to receive a signal representing a detected magnetic field from at least one of the magnetoresistance elements.
