Abstract

Capteur Hall à courant tournant comportant plusieurs contacts de courant ou de mesure (1-4) pour appliquer un courant de fonctionnement (I) et prélever une tension Hall, avec une couche conductrice de courant (110) traversée par le courant de fonctionnement (I) et une couche adjacente (120, 410, 420) entre lesquelles, lorsque le Capteur Hall (100) fonctionne, on a une zone de charges d'espace (130) qui limite le passage du courant dans la couche conductrice de courant (110) à une zone conductrice de courant. La couche adjacente (120, 410, 420) comporte plusieurs contacts (221-224 ; 421-424) auxquels est appliquée une tension dimensionnée pour que le courant de fonctionnement (I) lorsqu'on alimente suivant une première direction et suivant la direction opposée, traverse une zone de conduction de courant essentiellement identique. »Rotating current Hall sensor comprising several current or measurement contacts (1-4) for applying an operating current (I) and sampling a Hall voltage, with a current conducting layer (110) through which the operating current (I) passes. ) and an adjacent layer (120, 410, 420) between which, when the Hall Sensor (100) is operating, there is a space charge region (130) which limits the flow of current in the current conducting layer (110 ) to a current conducting area. The adjacent layer (120, 410, 420) has several contacts (221-224; 421-424) to which is applied a voltage sized so that the operating current (I) when supplied in a first direction and in the opposite direction , passes through an essentially identical current conduction zone.
