A magnetic sensing device includes a first electrode, a second electrode, a first magnetic shield, a second magnetic shield, and a sensor. The first magnetic shield forms at least a portion of the first electrode. The second magnetic shield includes a first region that forms at least a portion of the first electrode and a second region that forms at least a portion of the second electrode. The sensor is positioned between the first and second magnetic shields and is electrically connected in series between the first and second electrodes.
