Abstract
A sensor package includes a magnetic field sensor, where the magnetic field sensor includes an in-plane sense element and a flux guide configured to direct a magnetic field oriented perpendicular to a plane of the magnetic field sensor into the plane. A current carrying structure is positioned proximate the flux guide and circuitry is coupled to the current carrying structure. The current carrying structure includes a continuous coil having multiple substantially parallel conductive segments connected by additional conductive segments oriented Perpendicular to the parallel conductive segments to form a continuous series of loops. The circuitry is configured to provide an electric current to the continuous coil such that the electric current flows through each of the parallel conductive segments, wherein the electric current generates a magnetic field, and the magnetic field is applied to the flux guide to recondition a magnetic polarization of the flux guide.
