Abstract :
The author describes an implicit steepest-descent method for stable convergent numerical analysis of nonlinear algebraic equations. First, he shows the equivalence between the charge-up method based on the virtual capacitors used in circuit simulation and the homotopic method studied in the field of nonlinear programming. Next, he describes the physical significance of the steepest-descent method in network simulation. Furthermore, he suggests an implicit steepest descent method and shows the analogy with the charge-up method. Finally, he applies this implicit method to nonlinear network analysis and verifies its availability. The applicability of the proposed approach to MOS-circuit simulation is mentioned
