摘　　要：通过引入两个RLC元包,本文提出了一种针对有损传输线驱动点导纳的γdn模型构造方法,只要有规律地增加RLC元包的个数,该模型很容易实现高阶扩展以适应工作频率和模型精度的要求,并保持等效后电路的稳定性和无源性.SPICE仿真结果表明该模型要比通常使用的开端等效p模型具有更高的精度.A realizable equivalent rd/n model for RLC interconnect driving point admittance is proposed in this paper. By introducing two formative RLC cells, the RLC interconnect which is modeled as a lossy transmission line can be accurately constructed and extended with these basic cells to meet the demand of given frequency and precision without the problems of instability or passivity. Simulation results show that this model can obtain a higher accuracy compared with the common used model open π.
