Patent number: 11598828Abstract: The present disclosure generally relates to a Wheatstone bridge array that has four resistors. Each resistor includes a plurality of TMR structures. Two resistors have identical TMR structures. The remaining two resistors also have identical TMR structures, though the TMR structures are different from the other two resistors. Additionally, the two resistors that have identical TMR structures have a different resistance area as compared to the remaining two resistors that have identical TMR structures. Therefore, the working bias field for the Wheatstone bridge array is non-zero.Type: GrantFiled: December 30, 2019Date of Patent: March 7, 2023Assignee: Western Digital Technologies, Inc.Inventors: Yuankai Zheng, Christian Kaiser, Zhitao Diao, Chih-Ching Hu, Chen-jung Chien, Yung-Hung Wang, Dujiang Wan, Ronghui Zhou, Ming Mao, Ming Jiang, Daniele Mauri
