Patent ID: 8436710

Claim:
An integrated circuit for information transfer, comprising: a substrate; at least one Hall element, which is one of integrated into the substrate and situated on the substrate; a first coil, which is situated essentially concentrically with respect to the Hall element and at a distance from the Hall element in the vertical direction and galvanically separated therefrom; and at least one second coil, which is situated essentially concentrically with respect to the Hall element and galvanically separated therefrom and situated at a distance from the Hall element and the first coil in the vertical direction, wherein the first coil and the second coil are electrically connected in series so that a current flow in a same direction results in the coils; at least one second Hall element, which is at least one of integrated into the substrate and situated on the substrate; a third coil, which is situated essentially concentrically with respect to the second Hall element and at a distance from the second Hall element in the vertical direction and galvanically separated therefrom; and a fourth coil, which is situated essentially concentrically with respect to the second Hall element and at a distance from the second Hall element and the third coil in the vertical direction, the coils being electrically connected in series so that a current flow results in a same direction in the third coil and the fourth coil which is opposite to the current flow in the first coil and the second coil.
