Ernesto Limiti

Università degli Studi di Roma "Tor Vergata", Italy

Ernesto Limiti (Roma, Italy, 1965) is full professor of Electronics in the Engineering Faculty of the University of Roma Tor Vergata since 2002, after being research and teaching assistant (since 1991) and associate professor (since 1998) in the same University. The scientific activity of Ernesto Limiti is focused on three lines, all belonging to the microwave and millimetre-wave electronics research area. The first one is related to characterisation and modelling for active and passive microwave/millimetre-wave devices. Regarding active devices, the research is oriented to small-signal, noise and large signal modelling. Regarding passive devices, equivalent-circuit models have been developed for interacting discontinuities, for typical MMIC passive components and to WG/CPW transitions analysis and design. For active devices, new methodologies have been developed for the noise characterisation and the subsequent modelling, and equivalent-circuit modelling strategies have been implemented both for small- and large-signal regimes for GaAs, GaN, SiC, Si, InP MESFET/HEMT devices. The second line is related to design methodologies and characterisation methods for low noise circuits. The focus is on cryogenic amplifiers and devices. Collaborations are currently ongoing with the major radioastronomy institutes within the frame of FP6 and FP7 programmes. Finally, the third line is in the analysis methods for nonlinear microwave circuits. In this line, novel analysis methods are developed, together with the stability analysis of the solutions making use of traditional approaches. A special focus is paid on high-efficiency power amplifiers. The above lines have produced more than 250 publications on refereed international journals and presentations within international conferences. Ernesto acts as a referee of international journals of the microwave and millimetre wave electronics sector and is in the steering committee of international conferences and workshops.
