Advanced Concepts: First-Order Nonlinear Circuits

In this chapter, some of the concepts introduced in Chap. 9 are extended to nonlinear first-order circuits, also making reference to potential functions for resistive circuits. In particular, some circuits with piecewise-linear nonlinearities (either original or obtained by approximation) are studied, showing the advantages of this kind of formulation, which makes it possible to find the solution analytically, whereas in the general case we usually have to resort to numerical solutions.
