"AMR sensors are chosen to be evaluated in low noise measurements with combined processing of DC and AC excitation field with respect to the arrangement of processing electronics. Circuit with a commercial AMR sensor HMC1001 and AD8429 preamplifier using flipping technique exhibited 1-Hz noise as low as 125 pT/sqrtHz. Without flipping, the 1-Hz noise increased to 246 pT/sqrtHz." . "Sensors & Their Applications XVII" . . "85464" . "3"^^ . .
