Abstract: A shield for an inductive position sensor is configured in shape to avoid compromising the inductive field variations related to the sensor's moving target. Said shield is shaped as at least one conductive strip and is laid along the direction of motion of the moving target. Said shield is arranged to prevent induced current in the shield that could affect the part of the inductive field used by the sensor. Improvements are also conferred by a demodulator circuit implementing a zero phase oscillator which simultaneously measures the inductance and the temperature of the sensor windings to reduce and compensate for the effects of the shield. Said conductive shield may also provide for the electrical connection to the far end of the winding. For multi-layer windings, connection of the winding closest to the shield to the lower impedance side of the demodulator also reduces the effect of the shield.

Abstract: A magnetic field sensor that includes a differential bridge in which each path of the bridge includes a first type of magnetic field sensing device and a second type of magnetic field sensing device. The first and second types of magnetic field sensing devices differ in the magnetic moment imbalance present in the synthetic antiferromagnets (SAFs) included in their reference layers such that that different types of devices produce a different response to perpendicular magnetic fields, but the same response to in-plane magnetic fields. Such different magnetic moment imbalances in the SAFs of magnetic field sensing devices included in a bridge allow for accurate sensing of perpendicular magnetic fields in a differential manner that also cancels out interference from in-plane fields. Techniques for producing such magnetic field sensing devices on an integrated circuit are also presented.
