Iterative solutions of the generalized diode equation

Abstract

For original paper 'Approximate analytical solution of generalized diode equation' by T.A. Fjeldy et al. see ibid., vol.38, no.8, p.1976-7, Aug. 1991. The authors significantly enhanced the efficiency with which one may solve the generalized diode equation in numerical circuit simulation programs. This study concluded that Newton-Raphson iteration is relatively ill-suited for this task. To the contrary, the commenter finds that Newton's method is comparable to that of Fjeldly et al. and discusses the merits of an alternative cubic step and two Newton steps.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
