Abstract
PURPOSE: A high S/N is obtained as a sensor circuit by connecting in series two magnetoresistive elements disposed parallel in proximity in a bias magnetic field. biasing the elements with a constant current and applying the composite output of both elements via 1/2 voltage dividing circuit and one of the element outpus via storage battery to a differnetial amplifier cirucit.
