Abstract:
A back-biased magnetic field sensor uses one or more magnetic field sensing elements upon a substrate, each outside of a substrate region in which magnetic field lines are near perpendicular to the substrate and outside of which magnetic field lines are not to the substrate. The back-biased magnetic field sensor can sense an approaching and/or a retreating ferromagnetic object.
