Abstract

PURPOSE: To improve the S/N of detection output by connecting in series two magnetoresistive elements disposed parallel in proximity in a bias magnetic field, biasing the leements with a constant current and applying the output via the connection point of the elements and the mid-point of a 1/2 voltage dividing circuit connected in parallel to the elements to a differnetial amplifier.
