Abstract:
1. An electronic device comprising: an integer number of n Hall effect regions, with n>1, wherein the n Hall effect regions are isolated from each other; wherein the electronic device comprises at least eight contacts in or on surfaces of the n Hall effect regions, wherein the contacts comprise a first and a second contact of each Hall effect region; wherein a first contact of the (k+1)-th Hall effect region is connected to a second contact of the k-th Hall effect region for k =1 to n−1, and a first contact of the first Hall effect region is connected to a second contact of the n-th Hall effect region; wherein the at least eight contacts comprise at least two contacts configured to function as supply contacts during a first operating phase of a spinning current scheme and to function as sense contacts during a second phase of the spinning current scheme and at least two contacts configured to function as sense contacts during the first operating phase of the spinning current scheme and to function as supply contacts during the second operating phase of the spinning current scheme; wherein each Hall effect region comprises one of the at least two supply contacts; and wherein each Hall effect region comprises one of the at least two sense contacts.
