Topological conditions for unique solvability of RLC op amp networks

Based on the nullor equivalent model of the ideal op amp, the solvability of RLC op amp networks are discussed and some practical problems are analyzed. Then several necessary and sufficient topological conditions for unique solvability are given and their proofs are shown in detail. These conditions have great applications in the analysis, synthesis and diagnosis of networks. Finally the solvability of an illustrative network are analyzed as an example.
