A magnetoresistive sensor system (400) to linearize a sensor transfer function is provided, wherein the system (400) comprises a magnetic field source (402), a magnetoresistive sensor having an easy axis (403), and a filter (404), wherein the magnetic field source (402) is adapted to emit an auxiliary magnetic field from an oscillating input signal (401), wherein the auxiliary magnetic field is orthogonal to the easy axis of the magnetoresistive sensor (403), wherein the.magnetoresistive sensor (403) is adapted to sense a signal associated to a superposition of an external magnetic field and the auxiliary alternating magnetic field, and wherein the filter (404) is adapted to filter the sensed signal. |
