完备完全树及其在Op-Amp电路分析中的应用

A NEW TOPOLOGICAL FORMULATION OF SYMBOLIC NETWORK FUNCTION OF IDEAL OP-AMP NETWORKS

介绍一种分析Op-Amp电路的拓扑公式和算法。与Mayeda算法相比,本算法不需要处理双图;也克服了完全树符号确定的困难。举例说明了该算法在电路分析中的应用。

A new and efficient algorithm for topological formulation of network function in symbolic form for an ideal Op-Amp linear network N is suggested. Each Op-Amp linear network N is modelled by nullors and the concept of perfect complete tree of a topological graph of the modelling N is introduced. Being different from Mayeda's algorithm the algorithm only needs to operate one graph and its procedure of determining the sign of each group of perfect complete trees generated is simple. In the end, an example is given to illustrate the application of this algorithm in the analysis of practical Op-Amp networks.
