Abstract: The present disclosure relates to an anomalous Hall sensor, including a Hall cross. The Hall cross includes a layer stack including a ferromagnetic layer. A first arm of the Hall cross formed in the layer stack extends in a first direction. A second arm of the Hall cross formed in the layer stack extends in a second direction perpendicular to the first direction. The anomalous Hall sensor includes a control circuit configured to apply current through the first arm and measure voltage across the second arm, and apply current through the second arm and measure voltage across the first arm. The anomalous Hall sensor further includes a processor configured to compute a component of an external magnetic field in a third direction perpendicular to the first and the second direction based on a combination of the measured voltages.

Abstract: A magnetic sensor includes a first bridge circuit including a plurality of magnetic field sensor elements, each configured to generate a sensor signal in response to the magnetic field impinging thereon. The first bridge circuit is configured to generate a first differential signal based on sensor signals generated by the plurality of magnetic field sensor elements. The plurality of magnetic field sensor elements include a first, second, and third pair of sensor elements. The first pair are arranged at center region of the magnetic sensor, the second pair are arranged at a first side region of the magnetic sensor and are displaced a first distance from the first pair, and the third pair are arranged at a second side region of the magnetic sensor, opposite to the first side region, and are displaced a second distance from the first pair that is substantially equal to the first distance.

Abstract: The present disclosure relates to magnetic field sensor circuit which includes a first bridge circuit including a first series connection of a first magneto-resistor and a second magneto-resistor, and a second bridge circuit including a second series connection of a third magneto-resistor and a fourth magneto-resistor. A first terminal between the first magneto-resistor and the second magneto-resistor of the first bridge circuit is coupled to a second terminal between the third magneto-resistor and the fourth magneto-resistor of the second bridge circuit. The coupled first and second terminals provide a first output signal of the magnetic field sensor circuit.

Abstract: A monitoring device of a sensor may obtain a first signal at a point on a first branch of a signal path of the sensor. The monitoring device may obtain a second signal at a point on a second branch of the signal path of the sensor and may monitor the first signal for first characteristics indicated by the first signal. The monitoring device may monitor the second signal for second characteristics indicated by the second signal. The monitoring device may determine whether a quantity of first characteristics indicated by the first signal without a particular quantity of second characteristics being indicated by the second signal reaches a threshold quantity of first characteristics. The monitoring device may assess functionality of the signal path based on whether the quantity of first characteristics indicated by the first signal without a particular quantity of second characteristics being indicated by the second signal reaches the threshold quantity of first characteristics.

Abstract: A sensor device includes at least one first sensor element that generates a first sensor signal based on sensing a varying magnetic field; at least one second sensor element that generates a second sensor signal based on sensing the varying magnetic field; a signal tracking circuit that generates a trigger signal having trigger pulses that are generated based on crossings of the first sensor signal with an adaptive threshold and extracts vibration relevant information using the first sensor signal and the second sensor signal; an output controller that generates an output signal having output pulses that are triggered by the trigger pulses during a non-vibration event and suppress the output pulses during an entire duration of a vibration event; and a vibration detection circuit that detects the vibration event based on the extracted vibration relevant information and indicates the vibration event to the output controller.
