Item type: Item , Device level model for trapping effects in GaN and GaAs devices for broadband data communication(2015) Guillermo Rafael-Valdivia; Zhiguo Su; Anthony Urquizo; Thalia MendozaIn this work, we propose a new non-linear equivalent circuit which is able to model the low frequency dispersion phenomena caused by the trapping effects in GaAs and GaN devices. Large signal pulsed measurements were used to extract the new model.Item type: Item , Modeling the frequency dispersion phenomena in GaN and GaAs devices for broadband data communication(2014) Guillermo Rafael-Valdivia; Zhiguo Su; Anthony Urquizo; Thalia MendozaA novel technique for modeling GaN and GaAs transistors for data communications is proposed. The technique can model one of the most critical phenomena in wideband communications, called frequency dispersion effects. Results of measurements reveal the accuracy of this model under small and large signal conditions.
