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…

Theoretical and experimental study of multilayer piezo-magnetic structure based surface acoustic wave devices for high sensitivity magnetic sensor

Huan Zhou, Abdelkrim Talbi, Nicolas Tiercelin, Olivier Bou Matar

This study addresses the experimental and theoretical investigations of piezomagnetic acoustic waves propagating along the surface of a piezoelectric substrate on which a magnetostrictive thin film is deposited. The main objective of this work is to design high sensitivity surface acoustic wave…

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…

Enhanced gold film-coupled graphene-based plasmonic nanosensor

Rana Nicolas, Thomas Maurer, Gaëtan Lévêque, P. Subramanian, Julien Proust, Jérémie Béal, Silvere Schuermans, Jean-Pierre Vilcot, Z. Herro, M. Kazan, Jerome Plain, Rabah Boukherroub, Abdellatif Akjouj, Bahram Djafari-Rouhani, Pierre-Michel Adam, Sabine Szunerits

In this work, a trilayer graphene is used as a thin non dielectric spacer with a high index of refraction, between Au film and Au NPs. Encouraged by the sharpness of the localized surface plasmon resonance LSPR induced by this system, we performed sensitivity measurements to refractive index change…

Doubly coded Costas signals for grating lobes mitigation

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Atika Rivenq

In this paper, a novel design scheme for radar signal is proposed. It is based on a modification of Costas codes design by increasing the frequency separation of frequency hops beyond the orthogonality condition. Indeed, Costas codes are well known for their good range-doppler properties. Their…
