摘要
针对平面四边形螺旋变压器,提出了一种新型T-型集总参数等效电路模型,所建立的模型包含所有的导线损耗和衬底的寄生损耗;采用并联的L-R和L-R-C网络,模拟了衬底的感性寄生效应;通过二端口网络分析和向量拟合方法得到模型中各元件的值。将变压器等效电路模型仿真数据与HFSS中电磁仿真数据进行对比,两者在0-20GHz频率范围内有很高的吻合度。
A new T-lumped-element equivalent circuit model of quadrilateral-shaped planar spiral transformers was presented.The model could accurately capture the substrate parasitic losses and conductor losses in the transformer windings.A parallel L-Rand L-R-C network model was used to characterize the substrate inductive parasitic effects.All the elements could be extracted by using two port network analytical method and vector fitting method.In order to verify the model's validity and accuracy,the simulated data of T-model was compared with the data of HFSS,and an excellent agreement had been found over a broad frequency range from 0to 20 GHz.
