MC flow graphs with hybrid nodes

Modified Mason-Coates flow graphs are introduced in this paper. Utilizing a simple rule, the voltage graph node can be expanded by the current node, which corresponds to the current of a branch oriented out of the incident circuit node. Then an arbitrary type of controlled source can be easily described by means of a flow graph. Applying these procedures, we obtain flow graphs of such circuits which are not commonly utilized, e.g. current conveyors or current feedback amplifiers.
