Caracterización no-lineal de dispositivos de un puerto basada en el principio de distorsión poli-armónica

Abstract

In this contribution the computation of a nonlinear diode model based on the Poly-Harmonic Distortion principle is described. The diode is composed of a non-linear conductance shunt connected to a non-linear capacitance, both of them quasistatic. The procedure used to extract these parameters only requires port-voltage and -current waveforms. The computed parameters of the model at different frequencies and power levels are presented and have been validated by comparing them with those obtained using a commercial circuit simulation tool (specifically with X-parameters). Unlike commercial CAD tools or conventional measurement set-ups the proposed technique can easily provide all the sensitivities related to DC components.
