A magnetic field sensor comprises a substrate, a first coil supported by the substrate and configured to carry a first current in a first direction to generate a first magnetic field, and a second coil supported by the substrate and nested within the first coil to form a gap between the first and second coils, the second coil configured to carry a second current in a second, opposite direction to generate a second magnetic field. A plurality of magnetic field sensing elements is configured to detect the first and second magnetic fields. A switching network is coupled to the plurality of magnetic field sensing elements and configured to connect the plurality of magnetic field sensing elements to form a first bridge circuit having a first arrangement of the magnetic field sensing elements and a second bridge circuit having a second arrangement of the magnetic field sensing elements.
