Abstract: Embodiments related to the generation of magnetic bias fields for magnetic sensing are described and depicted. In one embodiment, a sensor includes at least one magnetosensitive element, and a magnetic body with an opening, the magnetic body comprising magnetic material magnetized mainly in a vertical direction, the magnetic body having inclined surface sections shaped by the opening, wherein the sensor is arranged atop the opening.

Abstract: A magnetic sensor may include a comparator to receive a first signal indicating a strength of a magnetic field sensed by a first sensing component of the magnetic sensor, receive a second signal indicating a strength of a magnetic field sensed by a second sensing component of the magnetic sensor, perform an error check associated with the first sensing component and the second sensing component, the error check being performed based on the first signal and the second signal, and provide an indication of a result of the error check. The magnetic sensor may include a protocol encoder to receive the first signal, receive the indication of the result of the error check, and provide an output that includes the indication of the result of the error check.
