Patent number: 7531883Abstract: A magneto-resistance transistor including a magneto-resistant element which may function as an emitter and a passive element which may function as a collector. The base may be interposed between the passive element and the magneto-resistant element, thereby coupling the passive element with the magneto-resistant element. A magnetic field of a given strength may be applied to at least a portion of the magneto-resistant transistor, the given strength determining a resistance in the at least a portion of the magneto-resistant transistor. Thus, by adjusting the given strength of the magnetic field, the resistance may be adjusted. Therefore, different emitter current inputs may be achieved with a fixed voltage. Further, a base current may vary with a controlled variation of the emitter current input.Type: GrantFiled: November 17, 2006Date of Patent: May 12, 2009Assignee: Industrial Technology Research InstituteInventors: Ying-Wen Huang, Chi-Kuen Lo, Yeong-Der Yao, Lan-Chin Hsieh, Jau-Jiu Ju, Der-Ray Huang
