Abstract: A method of sensing a rotation speed of an encoder includes generating measurement values by a plurality of sensor elements in response to sensing a magnetic field, where the plurality of sensor elements are grouped into a first shifted pair, a central pair, and a second shifted pair; generating a first shifted differential measurement signal based on the measurement values generated by the first shifted pair, a central differential measurement signal based on the measurement values generated by the central pair, and a second shifted differential measurement signal based on the measurement values generated by the second shifted pair; and generating an output signal based on detecting the first shifted differential measurement signal, the central differential measurement signal, and the second shifted differential measurement signal crossing at least one threshold.

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.

Abstract: A receiver includes a receiver circuit to receive a first transition in a first direction, a second transition in a second, different direction after the first transition and a third transition in the first transition after the second transition of a signal. A first time period between the first and third transitions is indicative of a datum to be received. The receiver circuit is also configured to determine a second time period between the first transition and a second transition and to determine an additional datum to be received based at least on the determined second time period between the first and second transitions. Using the determined second time period allows for more information to be received in a reliable manner.

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.
