热敏电阻特性的线性化方法

讨论几种负温度系数(NTC)热敏电阻特性的线性化方法。首先,论文中会介绍一些关于NTC热敏电阻的理论知识和特性曲线。然后,会介绍几种模拟线性化方法。最后,电阻模式线性化和桥梁网络线性化方法将被详细讨论并在软件LTSpice和MATLAB上分别进行模拟,通过实验模拟来验证这两种线性化的实际效果,并进行比较。

Linearization of the Thermistor Characteristics

The linearization of a NTC thermistor is presented. Firstly, the theory and the characteristics of the NTC thermistors are discussed. Secondly, the introduction of the varied methods for analogue linearization of thermistors is followed. Then, the two methods: Resistance mode linearization and Bridge network linearization are used to linearize a NTC thermistor. After theory analysis, the circuits based on the two methods are simulated by LTSpice and MTALAB, respectively.
