硅磁敏三极管二维差分电路是在一硅芯片的x,y轴上对称地设置四只硅磁敏三极管的集成式磁电转换器件。在x、y轴上的各两只硅磁敏三极管组合成两对互为垂直的差分电路。这种电路可应用于二维磁矢量检测,四象限角度测量和定方位角以及直角坐标与极坐标之间的模拟变换。本文介绍这种电路的设计、结构,特性和应用领域。 Two-dimensional differential circuit of silicon magnetostrictive transistor is an integrated magnetoelectric conversion device in which four silicon magneto-sensitive triodes are symmetrically arranged on the x and y axes of a silicon chip. In the x, y axis of the two silicon magneto-sensitive triode into two mutually perpendicular differential circuit. This circuit can be applied to two-dimensional magnetic vector detection, four-quadrant angle measurement and azimuth and rectangular coordinates and polar coordinates between the analog conversion. This article describes the design, structure, characteristics, and application areas of this circuit.
