摘　　要：针对霍尔传感器自身固有的零位特性,对其产生的零位误差进行分类和深入分析,零位误差的种类是多样的,构成的因素也各不相同,只有对其影响实施有效遏制才能保证测试的精度,零位误差是其自身所不能克服的。通过对各类误差的成因、特点及影响的全面剖析,依据各自的特点,制定了相应的应对措施,针对不同类型的零位误差,提出了具体的电路补偿方案。各项补偿方法简单实用,易于实施,可以有效控制零位误差对测试的影响,保证了霍尔传感器在较高测试精度要求下仍然能够正常工作,获得了满意的补偿效果。In view of the inherent characteristics of zero of the Hall sensor, classify and analysis the zero error. There are many kinds of zero error which causes by different factors. It is necessary to stem the influence effectively for keeping the of the testing accuracy. Zero error can not be overcome by its own. Based on all kinds of error cause, analysis the characteristics and the influence of comprehensive. According to their respective characteristics, formulate the corresponding countermeasures. In view of the different types of zero error, puts forward the specific circuit compensation scheme. The compensation method is simple, practical and easy to implement, which can effectively control the influence of zero error of the test. Ensure the hall sensor will still be able to work under high testing accuracy and obtained the satisfactory result of compensation.
