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 one half period of the magnetic field.
