发明名称 Adjustment of a magneto-resistive angle sensor
摘要 The present invention relates to an angle sensor and a method for adjustment of an angle sensor. The angle sensor has two bridge circuits ( 1, 2 ), at which a pair of voltage values (U<SUB>1</SUB>, U<SUB>2</SUB>) is measurable during an angle measurement. The pair of voltage values are used together with at least one correction value for the computation of an angle. The angle sensor also has an analysis circuit that is provided for the computation of the correction value from several of the pairs of voltage values (U<SUB>1</SUB>, U<SUB>2</SUB>). The pairs of voltage values lie on the periphery of a circle or an ellipse when respectively plotted against each other, and the correction value is derived from a center point computation of the circle of the ellipse.
