Claim 0:
1. A magnetic field sensor, comprising:
a plurality of magnetoresistance sense elements coupled together as a first circuit to sense a magnetic field, wherein each magnetoresistance sense element of the plurality of magnetoresistance sense elements includes a first ferromagnetic layer and a second ferromagnetic layer separated by an insulating barrier layer, wherein portions of a first magnetoresistance sense element and a second magnetoresistance sense element are electrically connected,
wherein the first magnetoresistance sense element and a third magnetoresistance sense element of the plurality of magnetoresistance sense elements share a common ferromagnetic layer such that a first portion of the common ferromagnetic layer is above either the first ferromagnetic layer of the first magnetoresistance sense element or the first ferromagnetic layer of the third magnetoresistance sense element and a second portion of the common ferromagnetic layer is below the other of the first ferromagnetic layer of the first magnetoresistance sense element or the first ferromagnetic layer of the third magnetoresistance sense element.
