A symbolic circuit analysis-oriented algorithm for finding a common tree of the current and voltage graphs

A fundamental problem of symbolic analysis when using the signal flow graph method is to find the common tree of the current and voltage graph (Gi and Gv, respectively), which can be further applied for testing. In this paper we present a novel method in order to determine a common tree of both graphs, which may be used to obtain the symbolic network transfer function when carrying out the small-signal analysis of linear(ised) circuits.
