Abstract
Methods and apparatus for positioning a magnetic field sensor IC package having a first channel for a planar magnetic field sensing element and a second channel for vertical magnetic field sensing element in relation to an axis of a ring magnet to provide a desired phase relationship between the first and second channels. In embodiments, positioning the sensor includes an offset angle and a displacement with respect to a centerline of the ring magnet.
