摘要
RTD交流小信号等效电路模型是分析RTD交流特性的基础,也是用网络分析仪测量S参数,拟合提取交流参数和计算截止频率fR的依据。精确、合理的等效电路模型有助于深入理解RTD的工作原理,也对RTD器件和RTD集成电路的设计起重要的指导作用。介绍了四种常见而又重要的RTD交流小信号等效电路模型。
AC small signal equivalent circuit model on RTD is the basis for analysing the AC characteristics of RTD, and also is the dependence of AC parameters extraction and cut-off frequency fR calculation from S-parameters measurement by network analyzer. An accurate and reasonable equivalent circuit model is helpful to understand deeply the operating principle of RTD, and is very important for the design of RTD device and RTD integration. There were four conven-tional and important AC small signal equivalent circuit models of RTD were presented.
