摘　　要：为改善线性霍尔元件的输出特性,提出了一种基于霍尔互补组合的差分式应用方法。在阐述霍尔差分式测量方法的原理和实际应用的基础上,分别给出了霍尔互补组合体的实现方法和实验结果。结果证明,霍尔元件的差分式应用方法具有增大输出电压幅度、抑制共模干扰和降低温度漂移的优点,有利于提高线性霍尔元件的稳定性和测量精度。To improve the output characteristics of linear Hall element, the differential application method based on Hall complementary combination is proposed. On the basis of describing the differential measuring principle and practical application, the implementing method and experimental result of Hall complementary combination are given. The result shows that this differential application increases the output voltage amplitude, suppresses common mode interference, and reduces the temperature drift; and it benefits to enhance stability and measurement accuracy of Hall elements.
