Abstract
In a Hall sensor in which a Hall element and elements serving as heat sources out of components of a circuit for driving the Hall element are arranged close to each other on a silicon substrate, two directions of control currents by spinning current for the Hall element are selected in a vector manner based on signals from temperature sensors arranged close to a periphery of the Hall element, thereby enabling the elimination of a magnetic offset caused by heat generation of the heat sources.
