THREE 3-CONTACT VERTICAL HALL SENSOR ELEMENTS CONNECTED IN A RING AND RELATED DEVICES, SYSTEMS, AND METHODS

摘要

A vertical Hall effect sensor having three Hall effect regions interconnected in a ring can be operated in a spinning scheme. Each Hall effect region has three contacts: the first Hall effect region includes first, second, and third contacts; the second Hall effect region has fourth, fifth, and sixth contacts, and the third Hall effect region has seventh, eighth, and ninth contacts. Interconnections between the Hall effect regions are provided such that a first terminal is connected to a third contact, a second interconnection is arranged between the second and fourth contacts, a third terminal is connected to the sixth contact, a fourth interconnection is arranged between the fifth and seventh contacts, a fifth terminal is connected to the ninth contact, and a sixth interconnection is arranged between the first and eighth contacts.
