Patent ID: 8829900

Claim:
A Hall effect device, comprising: a conductive substrate having a first doping type; one or more tubs having a second doping type different than the first doping type; a first plurality of force and sense contact pair comprising multiple force contacts and multiple sense contacts disposed along a first line; a second plurality of force and sense contact pair comprising multiple force contacts and multiple sense contacts disposed along a second line intersecting the first line; a plurality of feedback circuits coupled to the plurality of force and sense contact pairs and configured to control a voltage potential at a sense contact of a force and sense contact pair of the Hall effect device by providing one or more feedback signals to the force contact of the sense contact pair; wherein processing measured feedback signals provided to a force contact of one or more output terminal contact pairs over a current spinning cycle provides a magnetic field value with a substantially zero point offset voltage; and wherein respective force and sense contact pair comprise distinct force contacts and sense contacts located within the one or more tubs, and wherein respective force contacts are configured to provide electrical energy to the Hall effect device and respective sense contacts are configured to provide an output signal from the Hall effect device.
