Abstract:
A magnetic field sensor includes one or more magnetic field sensing elements and a back-biased magnet arranged to avoid saturation of the one or more magnetic field sensing elements, particularly when the one or more magnetic field sensing elements comprise one or more magnetoresistance elements. The one or more magnetoresistance elements can be arranged in a resistor bridge.
