In the field of circuit simulation, homotopy methods have been studied by many researchers to overcome the convergence problem in DC operating point analysis. There are several types of homotopy methods. Among them, the variable-gain homotopy method has been studied very actively mainly in Europe and the United States. In this letter, we propose an effective technique for improving the computational efficiency of the variable-gain homotopy method. We also prove the global convergence property of the proposed algorithm.
