LOW-CONSUMPTION, AMR-TYPE, INTEGRATED MAGNETORESISTOR |
| 摘要 |
An integrated magnetoresistive sensor (20; 30; 40) of an AMR (Anisotropic Magneto Resistance) type, formed by a magnetoresistive strip (24) of ferromagnetic material and having an elongated shape with a preferential magnetization direction (EA). A set/reset coil (22) has a stretch (34a, 34b), which extends over and transversely to the magnetoresistive strip. A concentrating region (23), also of ferromagnetic material, extends over the stretch of the set/reset coil so as to form a magnetic circuit for the field generated by the set/reset coil during steps of refresh and maintenance of magnetization of the magnetoresistive coil. |

1. An integrated magnetoresistive sensor of an AMR (Anisotropic Magneto Resistance) type, comprising:
a magnetoresistor including a magnetoresistive strip with an elongated shape and having a preferential magnetization direction; a set/reset coil having a stretch extending transversely to the magnetoresistive strip; and a concentrating region of ferromagnetic material, wherein the magnetoresistive strip and the concentrating region extend over opposite sides of the stretch of the set/reset coil. |
