Abstract
A Hall element sensor circuit in one embodiment includes a Hall element, a Hall element source, a switch matrix operatively connected to the Hall element and the Hall element source to establish a spinning current in the Hall element and to receive a Hall element signal from the Hall element based upon the spinning current, a front end amplifier including a first input operatively connected to a first switch matrix output and a second input operatively connected to a second switch matrix output, and at least one voltage source operatively connected to the front end amplifier at a location in the Hall element sensor circuit between the switch matrix and the front end amplifier.
