Active Network "Root Tree" Reasearch And Application

The circuit analysis is the main constituent and the foundation of circuit design. Nowadays, along with the large scale integrated circuit development, the massive Components and the line causes the circuit analysis all the more to be complex. Moreover some new Components'application, for example in order to analyze the electronic circuit, introduces the controlled power source in the circuit component family, for realizes the gyrator in the integrated circuit which the inductance proposed, but also has the operational amplifier, the impedance transformer, impedance invertor and so on, the especially active filter in integrated circuit widespread applications, this causes the early circuit analysis method no longer to adapt the present analysis demand. This topic basis existing quite convenient directed graph the root tree analytic method, in view of each kind of circuit component, each active element concomitance directed graph has conducted the thorough research in particular, and proposed the rationality operational amplifier directed graph model, solved the problem of the unable to analysis active filter by the root tree law. And this topic based on the algorithm of spanning all trees in undirected graph, proposed one kind method in spanning all root trees, 2- tree in the directed graph. At last realize the application of root tree method in analysis active network by computer.
