Abstract / Hauptanspruch
A magnetic angle sensor device and a method for operating such device is provided. The magnetic angle sensor device includes a shaft rotatable around a rotation axis; a magnetic field source coupled to the shaft; a first magnetic angle sensor configured to generate a first signal that represents a first angle based on a first diametric magnetic field from the magnetic field source applied to the first magnetic angle sensor; a second magnetic angle sensor configured to generate a second signal that represents a second angle based on a second diametric magnetic field from the magnetic field source applied to the second magnetic angle sensor; and a combining circuit configured to determine a combined rotation angle based on the first signal and on the second signal.
