On piecewise-linear approximation of nonlinear mappings containing Gummel-Poon models or Schichman-Hodges models
K. Yamamura · IEEE Transactions on Circuits and Systems I Fundamental Theory and Applications · 1992
An effective technique for the piecewise-linear approximation of nonlinear mappings containing Gummel-Poon models or Shichman-Hodges models is presented. The basic idea is to exploit the pairwise-separability of the nonlinear mappings containing these nonseparable models. The proposed approximation is much more effective than the conventional piecewise-linear approximation using a simplicial subdivision.>
