Finding DC operating points of nonlinear circuits is an important problem in circuit simulation. The Newton-Raphson method employed in SPICE-like simulators often fails to converge to a solution. To overcome this convergence problem, homotopy methods have been studied from various viewpoints. There are several types of homotopy methods, one of which
succeeded in solving bipolar analog circuits with more than 20000 elements
with the theoretical guarantee of global convergence. In this paper, we propose an improved version of the homotopy method that can find DC perating points of practical nonlinear circuits smoothly and efficiently. Numerical examples show the effectiveness of the proposed method. |
