摘　　要：基于物理原理,对石墨烯螺旋电感提出了一种改进的等效电路模型,该模型在传统π模型的串联支路中增加了RC并联网络.并结合分析法和优化法,对此模型提出了一种参数提取方法.结果表明,在1～40 GHz频率范围内,测试所得S参数和模型仿真所得S参数能够高度地吻合.An improved equivalent circuit model for graphene spiral inductors based on physical principles is presented in this letter. The model is a π-circuit w ith additional parallel RC netw ork in the series branch. A parameter extraction approach for proposed model,w hich combines the analytical approach and empirical optimization procedure,is also investigated. Good agreement is obtained betw een the simulated and measured S-parameters up to 40 GHz.
