Summary:
Hybrid equations are often used in the theoretical study of nonlinear resistive circuits because they have an easily analyzed structure. They are also advantageous in the numerical analysis of nonlinear resistive circuits because they consist of a small number of variables and are separable. However, the hybrid equations are seldom used in practical application because their formulation is difficult. In this paper, we propose a simple method for formulating the hybrid equations using SPICE. In the proposed method, we only perform the transient analysis of SPICE to a linear circuit that is obtained through a small modification to the original circuit. It is also shown that state equations of nonlinear dynamic circuits can also be formulated by the proposed method.
