CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA recently proposed, technology-independent model is adopted for small- and large-signal performance prediction of PHEMT devices. The model is based on the definition of a quasi-static associated device, which is controlled by means of equivalent voltages, and can be easily identified from conventional DC and small-signal differential parameter measurements, without involving nonlinear optimization procedures. Experimental results for a GaAs PHEMT confirming the model accuracy at high operating frequencies are provided in the paper and compared with the prediction capability of two different models: the behavioral Nonlinear Discrete Convolution model and the equivalent-circuit based TriQuint’s Own Model provided by the foundry.
