Some Network-Theoretic Properties of Nonlinear DC Transistor Networks
Irwin W. Sandberg, Alan N. Willson · Bell System Technical Journal · 1969
This paper extends, in several directions, some of the results of earlier work concerned with the existence and uniqueness of solutions of the dc equations of nonlinear transistor networks. In particular, here we develop techniques which enable us to deal directly with a more complicated transistor model.
