Abstract
A magnetoresistive angular sensing method is disclosed. In a first mode, a first dc external magnetic field in a predetermined direction is applied to an angular sensor arrangement in which the external magnetic field dominates over a magnetic field generated by an input device an angular position of which is to be sensed. In a second mode, a second external magnetic field is applied to the angular sensor. Outputs of the angular sensor arrangement in the two modes are processed to determine an angular orientation of the input device with offset voltage compensation.
