Abstract: An alignment device may obtain a set of analog-to-digital converter (ADC) signals provided by an angle sensor operating in a homogeneous test mode. The set of ADC signals may be associated with a rotation of a target magnet relative to the angle sensor. The alignment device may identify a maximum ADC signal value based on the set of ADC signals. The alignment device may selectively position, by the alignment device, at least one of the angle sensor or the target magnet based on the maximum ADC signal value.

Abstract: Magnetic field sensors and sensing methods are provided. A magnetic sensor configured to measure a magnetic field whose magnitude oscillates between a first extrema and a second extrema. The magnetic sensor includes a plurality of magnetic field sensor elements, each configured to generate a sensor signal in response to the magnetic field impinging thereon. The plurality of sensor elements are grouped into a first group from which a first measurement signal is derived and a second group from which a second measurement signal is derived, and the first measurement signal and the second measurement signal having phase difference of 90°. The magnetic sensor further includes a sensor circuit configured to receive the first measurement signal and the second measurement signal, and apply a signal conversion algorithm thereto to generate a converted measurement signal having an increased frequency with respect to the first measurement signal and the second measurement signal.

Abstract: Magnetic field position sensors and sensing methods are provided. A magnetic field position sensor includes at least two magnetic field sensor elements configured to generate sensor signals in response to a magnetic field, where the at least two magnetic field sensor elements are sensitive to a same magnetic field component of the magnetic field, and a sensor circuit configured to generate a differential measurement signal, substantially independent from homogeneous external magnetic stray fields, based on the sensor signals.

Abstract: The innovative concept described herein relates to a magnetic angle sensor system having a rotatable shaft, a permanent magnet coupled to the rotatable shaft, and a magnetic field sensor arranged opposite the permanent magnet, wherein the magnetic field sensor is configured to detect a magnetic field prevailing in its detection region. The magnetic angle sensor system comprises means for reducing and/or compensating for an inhomogeneous stray field component of a per se homogeneous external magnetic stray field.

Abstract: The present disclosure relates to a design for operating an angle sensor. A first sensor signal is output from a first sensor element on the basis of a magnetic field, which is dependent on an angle of rotation of a measurement object, at the location of the first sensor element. A second sensor signal is output from a second sensor element on the basis of the magnetic field that is dependent on the angle of rotation of the measurement object at the location of the second sensor element. During a calibration mode of the angle sensor, in which a rotation of the measurement object is performed, a first offset value of the first sensor signal, a second offset value of the second sensor signal and an amplitude correction value are determined on the basis of signal amplitudes of the first and second sensor signals. The first and second offset values ascertained during the calibration mode and the amplitude correction value are stored for use in an operating mode of the angle sensor.

Abstract: Magnetic field sensor devices, corresponding systems and corresponding methods are discussed where a plurality of magnetic field sensors senses a magnetic field. An evaluation circuit generates a first signal component associated with a periodicity of a magnetic field, and a second signal component at least for periods of the magnetic field exceeding a threshold period length, the second signal component having a resolution smaller than the first signal component.
