Non-Linear Large-Signal Scattering Parameters: Theory and Applications
Jeffrey Jargon, Kuldip Gupta, Donald C. DeGroot
We introduce nonlinear large-signal scattering parameters, a new type of frequency-domain mapping that relates incident and reflected signals for sparse-tone inputs. We present a general form of nonlinear large-signal scattering parameters and show that they reduce to classic S-parameters are also introduced, and equations relating the different representations are derived. We illustrate how nonlinear circuit, specifically a single-diode 1 GHz frequency-doubler. For the case where a nonlinear model is not readily available, we developed a method of extracting nonlinear large-signal scattering parameters obtained with artificial neural network models trained with multiple measurements made by a nonlinear vector network analyzer equipped with two sources.
