ABSTRACT:
An inventive Hall element formed from semiconductor material is disclosed. The inventive Hall element comprises a plurality of interconnected portions formed in a common semiconductor layer. Depending on how the portions are interconnected, the Hall element may detect the sum or difference of magnetic field values. The invention enables the realization of very large Hall elements which can be used in electrical meters to measure a magnetic field produced by an electric current.
