Abstract
A magnetic sensing device is disclosed. The magnetic sensing device may have an integrated circuit and a magnetic sensor. A magnetic buffer layer of material may be deposited between the integrated circuit and the magnetic sensor to shield the magnetic sensor from stray electromagnetic fields generated by the integrated circuit. The magnetic buffer layer may also absorb electromagnetic fields generated by other internal sources of the magnetic sensing device.
