Abstract
A magnetic field sensor includes a phase-locked loop to receive a measured magnetic field signal formed from sensing element output signals of a plurality of magnetic field sensing elements in response to a magnetic field. The phase-locked loop is configured to generate an angle signal having a value indicative of the angle of the magnetic field. Associated methods are also described.
