A superheterodyne 300 GHz wireless link for ultra-fast terahertz communication systems

Iulia Dan, Guillaume Ducournau, Shintaro Hisatake, Pascal Szriftgiser, Ralf-Peter Braun, Ingmar Kallfass

A superheterodyne transmission scheme is adopted and analyzed in a 300 GHz wireless point-to-point link. This was realized using two different intermediate frequency (IF) systems. The first uses fast digital synthesis which provides an IF signal centered around a carrier frequency of 10 GHz. The...

Demonstrating full integration process for electroactive polymer microtransducers to realize soft microchips

Lauréline Seurre, Kätlin Rohtlaid, Giao T. M. Nguyen, Caroline Soyer, Sofiane Ghenna, Sébastien Grondel, Frederic Vidal, Barthelemy Cagneau, Cedric Plesse, Eric Cattan

Actuation and sensing with electroactive polymers should be a chance for flexible MEMS but their micromachining and integration are still not mature. Some innovative materials and microfabrication processes are still expected. In this paper, a first full elaboration of polymeric microtransducers (...

High-Frequency Noise Characterization and Modeling of Graphene Field-Effect Transistors

Marina Deng, Dalal Fadil, Wei Wei, Emiliano Pallecchi, Henri Happy, Gilles Dambrine, Magali de Matos, Thomas Zimmer, Sébastien Frégonèse

This article presents the small-signal and noise characterization of different technologies based on chemical vapor deposition (CVD) and silicon-carbide (SiC) graphene field-effect transistors (GFETs). The noise model, built on noise figure measurements under 50 Ω using the F 50 method, was...

A 300 GHz data communication receiver using plasma-wave FET detector in 65nm CMOS

Kefei Wu, Marwah Shafee, Philippe Le Bars, Walaa Sahyoun, Stéphane Blin, Guillaume Ducournau, Wojciech Knap, Mona Mostafa Hella

This paper presents a fully integrated receiver for 300 GHz communication using plasma-wave field effect transistor (FET) detector in digital 65 nm CMOS technology (fT/fmax=170/230 GHz). Besides the detector, the receiver chain includes an on chip patch antenna and a broadband base-band amplifier....
