HALL SENSOR AND COMPENSATION METHOD FOR OFFSET CAUSED BY TEMPERATURE DISTRIBUTION IN HALL SENSOR

摘要

The present invention relates to a Hall sensor in which a Hall element and elements serving as heat sources out of components of an operation circuit for the Hall element are arranged close to each other on a silicon substrate. According to the present invention, two directions of control currents by spinning current for the Hall element are selected in a vector manner based on signals from temperature sensors to be arranged adjacent to a periphery of the Hall element, thereby enabling the elimination of a magnetic offset caused by heat generation of the heat sources. The Hall sensor comprises: a semiconductor substrate; the hall element; two pairs of terminals; the element; and the temperature sensors.
