ABSTRACT:
An angle measurement system including a magnet coupled to a rotating member and adapted to provide a magnetic field which rotates with the rotating member about a rotational axis of the rotating member, and an integrated circuit angle sensor disposed within the magnetic field at a radially off-center position from the rotational axis. The integrated circuit angle sensor includes first and second bridges of magneto resistive elements configured to respectively provide first and second signals representative of substantially orthogonal first and second directional components of the magnetic field and together representative of an angular position of the rotating member, and a set of adjustment parameters for adjusting attributes of the first and second signals having values selected to minimize errors in the first and second signals.
