Abstract
A system includes a magnet configured to produce a magnetic field, the magnet having an asymmetric magnetization configuration that produces a distinct feature in the magnetic field. The asymmetric magnetization configuration can be produced via an asymmetric physical characteristic, nonuniform magnetization strengths, nonuniform magnetization distributions, off-centered magnet, and so forth. Magnetic field sensors are configured to produce output signals in response to the magnetic field, the output signals being indicative of the distinct feature in the magnetic field. A processing circuit receives the output signals and determines a rotation angle for the magnet using the output signals, the rotation angle having a range of 0-360°.
