“…Given the high computational costs of the Spice models, their approximation through cheaper functions is the first step in many numerical procedures on microelectronic circuits. Within the vast set of methods proposed by researchers on the matter (Ampazis & Perantonis, 2002a;Daems et al, 2003;Friedman, 1991;Hatami et al, 2004;Hershenson et al, 2001;McConaghy et al, 2009;Taher et al, 2005;Vancorenland et al, 2001) in Table 3 we report a numerical comparison between two well reputed fitting methods and our proposed Reverse Spice based algorithm (for short RS). The methods are Multivariate Adaptive Regression Splines (MARS) (Friedman, 1991), i.e.…”
