Abstract— Finding the dc operating points is an important task. Recently, an efficient homotopy method termed the Newton fixed-point homotopy method (NFPH) has been proposed to find the dc operating points of MOS transistor circuits. This method is not only efficient but also globally convergent for any initial point. However, how to effectively implement the proposed MOS NFPH method has been an open problem. In this paper, an effective and practical “Embed” implementation algorithm is proposed for the MOS NFPH method.Numerical examples show that the MOS NFPH method with this proposed “Embed” implementation method is more efficient for finding dc operating points than the conventional MOS ATAN-SH method.
