Blind primary user identification in MIMO cognitive networks

A. Ghosh, W. Hamouda, Iyad Dayoub

Early detection of primary users presence is one of the most important tasks for cognitive communication. Also, in cognitive settings cognitive nodes may receive signals from primary users and from other cognitive users simultaneously. For such scenario, we propose primary user signal detection…

A 285 GHz sub-harmonic injection locked oscillator in 65nm CMOS technology

J. Moron Guerra, A. Siligaris, Jean-Francois Lampin, Francois Danneville, P. Vincent

A 285 GHz Sub Harmonic Injection Locked Oscillator (SHILO) is presented using a standard 65nm CMOS process. The architecture of this oscillator is based on the differential LC tank with push-push but adapted to obtain a third harmonic oscillation. The output power is -19 dBm at 285 GHz for a dc…

Rotational temperatures in RF plasma of Ar-H2O mixtures at low and moderated pressure

Adriana Annusova, Jaroslav Krištof, Corinne Foissac, Pavel Veis, Philippe Supiot

An Ar-H2O discharge with Ar content from 0 to 95 % at 67 and 266 Pa have been studied by optical emission spectroscopy. The plasma was excited at 27 MHz by a helical cavity with a power set at 30 W. The rotational temperatures of N2(C3Πu) and OH(A2 Σ + ) emitters were determined through spectral…

Doped semiconductor nanocrystal junctions studied by Kelvin probe and non-contact atomic force microscopy

Lukasz Borowik, Thuat Nguyen-Tran, D. Deresmes, Heinrich Diesinger, Pere Roca I Cabarrocas, Thierry Melin

Semiconductor junctions are the basis of electronic and photovoltaic devices. Here, we investigate junctions formed from highly doped (ND~10^20-10^21 cm-3) hydrogen-passivated silicon nanocrystals (NCs) in the 2-50nm size range, using non-contact atomic force microscopy coupled to Kelvin probe…

High frequency noise characterisation of graphene FET Device

D. Mele, S. Fregonese, Sylvie Lepilliet, E. Pichonat, Gilles Dambrine, H. Happy

RF GFET devices have been processed on SiC wafer using Al2O3 as a gate oxide. These devices have been characterised with DC, S parameter and high frequency noise measurement (NF50). The noise parameters have been extracted in order to evaluate the graphene material for RF applications. This GFET…
