霍尔元件是一种半导体电磁效应的元件,元件结构如图1所示。在矩形半导体薄片上对称地焊有四根引线,其长边方向上的两根称为电流极引线,其两旁中点的两根称为霍尔输出端引线。当电流极引线通入电流I,并在垂直于矩形半导体薄片方向上加 Hall element is a semiconductor electromagnetic effect of components, component structure shown in Figure 1. Four rectangular leads are symmetrically welded on a rectangular semiconductor sheet. Two of them in the long-side direction are called current pole leads, and two of the two mid-points are called Hall output lead wires. When the current lead leads through the current I, and perpendicular to the direction of the rectangular semiconductor sheet plus
