Abstract
A sensor device (10) is described. The sensor device (10) comprises a laterally arranged double coil (20) with a first coil (30a) and a second coil (30b), wherein first windings (40a) of the first coil (30a) and second windings (40b) of the second coil (40b) are arranged in a spiral shape. The first windings (40a) from a first center point (50a) lead to a common region (60) and the second windings (40b) from a second center point (50b) lead to the common region (60) as well. At least one magnetic field sensor (70, 72a, 72b) is disposed on the laterally arranged double coil (20).
Claims9
A sensor device comprising:
- a laterally arranged double coil with a first coil and a second coil, wherein first windings of the first coil and second windings of the second coil are arranged in a spiral shape and wherein the first windings lead from a first center point to a common region and the second windings lead from a second center point to the common region;
- and a plurality of magnetic field sensors disposed on the laterally arranged double coil, wherein the plurality of magnetic field sensors are an interconnection of a plurality of individual sensors, wherein a common effective point of the magnetic field sensors is located below a bond pad, and wherein the magnetic field sensors are disposed in the center points of the corresponding coil.
