Description
We analyzed the detectivity in different type of planar Hall magnetoresistive sensors by varying parameters such as power operating mode, geometry, sensor stack, and temperature. Voltage noise characteristics in 0.5-200 Hz and sensor sensitivity are measured in an unshielded environment. We observed less significant Barkhausen noise in planar Hall magnetoresistive sensor configuration. We achieved the best magnetic field detectivity reaching to 521 pT/√Hz at 100 Hz, using a NiFe/Cu/IrMn-stacked multiring planar Hall magnetoresistive sensor. [1]
