本文提出了一种有源网络的分割——重建技术:将一个有源网络分割为集总元件子网络和器件子网络,依据各子网络的不定散射矩阵,通过浮地端口的对接与封禁,建立起原网络的散射矩阵,借以完成原网络的分析与设计。利用本方法能处理具有任意复杂拓扑结构的有源电路。文中列举了几个应用实例。 In this paper, an active network segmentation-reconstruction technique is proposed: an active network is divided into a lumped component sub-network and a device sub-network. According to the indefinite scattering matrix of each sub-network and the floating port docking and blocking, Establish the original network of scattering matrix, in order to complete the original network analysis and design. The method can be used to deal with any complex topology of the active circuit. The article lists a few examples of applications.
