Abstract:
A magneto-resistive angle sensor includes a first half bridge circuit including a first magneto-resistive element and a second magneto-resistive element, and a second half bridge circuit having a third magneto-resistive element and a fourth magneto-resistive element, wherein the first, second, third, and fourth magneto-resistive element are arranged parallel to a x′/y′-plane of a Cartesian reference system with an x′-axis and y′-axis, both orthogonal to each other. The geometrical gravity centers of the first and the second magneto-resistive elements of the first half bridge circuit and the geometrical gravity centers of the third and the fourth magneto-resistive elements of the second half bridge circuit have an identical x′-coordinate, wherein the sum of the value of the geometrical inertia moment of the first magneto-resistive element around the y′-axis, the negative value of the geometrical inertia moment of the second magneto-resistive element around the y′-axis, the value of the geometrical deviation moment of the third magneto-resistive element in the x′/y′-plane and the negative value of the geometrical deviation moment of the fourth magneto-resistive element in the x′/y′-plane vanishes within a tolerance range. Further, the sum of the value of the geometrical inertia moment of the third magneto-resistive element around the y′-axis, the negative value of the geometrical inertia moment of the fourth magneto-resistive element around the y′-axis, the negative value of the geometrical deviation moment of the first magneto-resistive element in the x′/y′-plane and the value of the geometrical deviation moment of the second magneto-resistive element in the x′/y′ vanishes within a tolerance range.
