A neural network approach for nonlinear modelling of LDMOSFETs
Zlatica Marinkovic,Giovanni Crupi,Antonio Raffo,Gianni Bosi,Gustavo Avolio,Vera Markovic,Alina Caddemi,Giorgio Vannini,Dominique Schreurs +8 more
TL;DR: Artificial neural networks are used to model the dependence of both DC drain current and intrinsic capacitances with respect to the intrinsic gate and drain voltages in a 10-W LDMOSFET.
Proceedings Article
Influence of the gate current dynamic behaviour on GaAs HEMT reliability issues
TL;DR: Reliability issues in GaAs pHEMTs are empirically investigated and it is shown that an exhaustive information for reliability analysis can be obtained only by looking at the gate current dynamic behaviour.
Proceedings ArticleDOI
A Small-Signal Parameter-Based Metric for Nonlinear Models of Electron Devices
TL;DR: A new metric for the estimation of large-Signal model accuracy is discussed, which is simply based on the comparison between de-embedded measurements and model predictions of small-signal Y-parameters versus the bias voltages at the intrinsic device ports.
Proceedings ArticleDOI
Experimental investigation of LF dispersion and IMD asymmetry within GaN based HEMT technology
Gustavo Avolio,Antonio Raffo,Dominique Schreurs,Valeria Vadala,S. Di Falco,Anne Lorenz,W. De Raedt,Bart Nauwelaers,Giorgio Vannini +8 more
TL;DR: In this paper, an experimental investigation of the low-frequency dispersion affecting the behavior of microwave devices is reported by exploiting two different measurement techniques and experiments have been performed on a GaN based HEMT.
Proceedings ArticleDOI
A new description of fast charge-trapping effects in GaN FETs
TL;DR: In this article, a nonlinear multi-bias model oriented to accurately predict the effects of charge-trapping in Gallium Nitride (GaN) HEMTs is proposed.
