1. A magnetic sensor system, comprising:
a magnetic sensor, wherein the magnetic sensor includes:
a first plurality of magnetoresistive sensor elements coupled together as a first circuit; and
a second circuit positioned adjacent to the first circuit and configured to receive a bipolar current signal from a bipolar current source coupled to the second circuit, wherein at least a portion of the second circuit is positioned adjacent to each magnetoresistive sensor element of the first plurality of magnetoresistive sensor elements; and
an analog to digital converter coupled to one or more of the first circuit and the second circuit,
wherein one or more of the bipolar current signal and the analog to digital converter is configured to eliminate at least a portion of 1/f noise generated from at least one magnetoresistive sensor element of the first plurality of magnetoresistive sensor elements.
