ABSTRACT
Frequently, it is useful to decompose a large circuit into subcircuits and to consider the subcircuits separately. Subcircuits are connected to other subcircuits using terminals or ports. Terminal and port representations of a subcircuit describe how that subcircuit will act when connected to other subcircuits [1,2]. Terminal and port representations do not provide the details of mesh or node equations because these details are not required to describe how a subcircuit interacts with other subcircuits. In this chapter, terminal and port representations of circuits are described. Particular attention is given
to the distinction between terminals and ports. Applications show the usefulness of terminal and port representations.
