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.

Abstract: A magnetic field sensor for sensing a direction of a magnetic field in an x-y plane, can include a first plurality of magnetic field sensing elements operable to generate a first plurality of magnetic field signals and a second plurality of magnetic field sensing elements operable to generate a second plurality of magnetic field signals. The magnetic field sensor can also include at least one sequence switches circuit operable to select ones of the first plurality of magnetic field signals and to select ones of the second plurality of magnetic field signals. The magnetic field sensor can also include a processing circuit operable to combine the selected ones of the first plurality of magnetic field signals and the selected ones of the second plurality of magnetic field signals to generate at least one sequential signal and to process the at least one sequential signal to generate an x-y angle signal indicative of a direction of the magnetic field in the x-y direction. An associated method is described.

Abstract: A magnetic field sensor has a plurality of vertical Hall elements arranged in at least a portion of a polygonal shape. The magnetic field sensor includes an electronic circuit to process signals generated by the plurality of vertical Hall elements to identify a direction of a magnetic field. A corresponding method of fabricating the magnetic field sensor is also described.
