Abstract

Abstract:

A concise quasi-linear model of the temperature offset for full Wheatstone-type bridges magneto resistive sensors is proposed based on the temperature-dependent of resistivity of four elements. In MATLAB environment, the simulation results of quasi-linear model agree well with the experimental results, indicating that the quasi-linear model is simple but efficient for the offset calibration, can explain the causes of the temperature offset for full Wheatstone-type bridges magneto resistive sensors, and can be applied to other sensors with full Wheatstone-type bridges structure.

Key words: full Wheatstone-type bridges structure, magneto resistive sensors, concise model of temperature offset

摘要：

基于惠斯通电桥式磁阻传感器4个电阻元件存在温度差异的事实, 提出一个惠斯通电桥式磁阻传感器零位温度漂移的简明准线性模型。在MATLAB环境下, 准线性模型的仿真结果与实验结果吻合, 验证了准线性模型的有效性, 为解释惠斯通电桥型磁阻传感器零位温度漂移的原因提供了清晰的思路, 此模型也可应用于其他具有惠斯通电桥结构的传感器。

关键词: 惠斯通电桥结构, 磁阻传感器, 零位温度漂移简明模型
