Abstract
An electronic device includes a number of n Hall effect regions with n>1, wherein the n Hall effect regions are isolated from each other. The electronic device also includes at least eight contacts in or on surfaces of the n Hall effect regions, wherein the contacts include: a first and a second contact of each Hall effect region. A first contact of the (k+1)-th Hall effect region is connected to the second contact of the k-th Hall effect region for k=1 to n−1, and the first contact of the first Hall effect region is connected to the second contact of the n-th Hall effect region. The at least eight contacts include at least two supply contacts and at least two sense contacts. Each Hall effect region includes at most one of the at least two supply contacts and at most one of the at least two sense contacts.
