Claim:
1. A method of operating a plurality of magnetic field sensors of a field sensor, the method comprising: sensing, by a field sensor including a plurality of magnetic field sensors, a magnetic response in a direction out of a plane defined by the plurality of magnetic field sensors of the field sensor, each magnetic field sensor including a sensing element having a first side and a second side, a flux guide disposed orthogonal to and spaced from the first side of the sensing element, and a plurality of reset lines positioned proximate the sensing element and adjacent to the flux guide, wherein the field sensor further includes control circuitry operably connected to each reset line and configured to selectively apply at least one current pulse to each reset line of the plurality of reset lines; selectively applying a plurality of current pulses to the plurality of reset lines; and generating a reset field to re-orient a magnetic domain in the flux guide, wherein the reset field is generated as a result of the selectively applied plurality of current pulses.
