On the use of Cann's model for nonlinear behavioral-level simulation

The use of Cann's model for modeling nonlinear circuits and systems is disc ussed in this paper. It is shown that this model has a nonphysical behavior for the small-signal regime in most cases (it has no some derivatives and, correspondingly, cannot be expanded in a Taylor series) and gives incorrec t predictions for nonlinear products. When nonlinearities are to be taken i nto account in the simulation (intermodulation, adjacent channel power, etc .), the use of Cann's model should be avoided or at least it should be used with extreme care.
