Abstract: An absolute position measurement system includes a multipole magnet including alternating magnetic poles extending along a multipole extension direction, the multipole magnet has a linear changing configuration relative to a linear path and produces a magnetic field having a field strength that undergoes a sinusoidal change along the linear path due to the alternating magnetic poles and a linear change along the linear path according to the linear changing configuration relative to the linear path; and a magnetic sensor configured to move along the linear path. The magnetic sensor includes a first sensor element arrangement configured to generate a first sensor signal, a second sensor element arrangement configured to generate a second sensor signal that is phase shifted with respect to the first sensor signal, and a processing circuit configured to calculate an absolute position of the magnetic sensor based on the first sensor signal and the second sensor signal.

Abstract: A magnetic sensor is 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 a phase difference based on different phases. 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.
