New Theorems on the Equations of Nonlinear DC Transistor Networks

Suppose a network is constructed by connecting in an arbitrary manner any number of transistors, diodes, resistors, and independent voltage and current sources. Without loss of generality, we may consider the network to have the canonical form shown in Fig. 1; that is, we may consider the network to be a multiport containing resistors and inde1713 1714 THE BELL SYSTEM TECHNICAL JOURNAL, OCTOBER 1970 Fig. 1--Canonical form of a transistor network.
