The Wiegand sensor is composed of this magnetic wire and the pick-up coil. As the output pulse voltage does not depend on a changing ratio of the applied magnetic field to switch the magnetization of the wire, the Wiegand sensor is used for to perform rotation and other detections. Recently, the Wiegand sensor has attracted significant attention as a power supply for battery-less operation of electric devices and for energy harvesting. In this study, we propose a concept of obtaining an intrinsic pulse voltage from the Wiegand sensor as its power source, and demonstrate its effectiveness in circuit simulation. The equivalent circuit for the Wiegand sensor is expressed by the intrinsic pulse voltage, internal resistance, and inductance of the pick-up coil. This voltage as a power source and circuit parameters are determined by MATLAB\/Simulink simulation. The output voltage calculated using the equivalent circuit of the Wiegand sensor agrees with the experimentally measured results.<\/jats:p>","DOI":"10.3390\/s19132991","type":"journal-article","created":{"date-parts":[[2019,7,8]],"date-time":"2019-07-08T03:01:31Z","timestamp":1562554891000},"page":"2991","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Output Characteristics and Circuit Modeling of Wiegand Sensor"],"prefix":"10.3390","volume":"19","author":[{"given":"Xiaoya","family":"Sun","sequence":"first","affiliation":[{"name":"Electrical and Computer Engineering, Yokohama National University, Yokohama 240-8501, Japan"}]},{"given":"Tsutomu","family":"Yamada","sequence":"additional","affiliation":[{"name":"Electrical and Computer Engineering, Yokohama National University, Yokohama 240-8501, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3680-728X","authenticated-orcid":false,"given":"Yasushi","family":"Takemura","sequence":"additional","affiliation":[{"name":"Electrical and Computer Engineering, Yokohama National University, Yokohama 240-8501, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1109\/MSSC.2010.936667","article-title":"Energy harvesting for autonomous wireless sensor networks","volume":"2","author":"Vullers","year":"2010","journal-title":"IEEE Solid State Circuits Mag."},{"unstructured":"Wiegand, J.R., and Velinsky, M.
