Title:
A MAGNETIC FIELD SENSOR AND METHOD OF FABRICATING A MAGNETIC FIELD SENSOR HAVING A PLURALITY OF VERTICAL HALL ELEMENTS ARRANGED IN AT LEAST A PORTION OF A POLYGONAL SHAPE
Document Type and Number:
WIPO Patent Application WO/2014/099283
Kind Code:
A3
Abstract:
A magnetic field sensor (100) has a plurality of vertical Hall elements (102a, 102b, 102c, 102d,102e,102e,102f) arranged in at least a portion of a polygonal shape. The magnetic field sensor includes an electronic circuit (108) to process signals generated by the plurality of vertical Hall elements to identify a direction of a magnetic field (109). A corresponding method of fabricating the magnetic field sensor is also described.
