Abstract
A magnetoresistive angular sensor and sensing method, in which an external magnetic field generator is used to provide a first mode in which a dc external magnetic field is provided in a predetermined direction and which dominates over the magnetic field generated by the input device being sensed. In a second mode, the external magnetic field is smaller. The angular sensor arrangement outputs from the two modes are combined, and this enables the input device angular orientation to be determined with offset voltage compensation.
