Temperature and damping effects on the frequency dependence of electrostatic force microscopy force gradients

R. Arinero, J. Trasobares, Pascal Girard, M. Ramonda, N. Clément

In this paper we demonstrate that depending on the surrounding ambient, which may be manifested by different damping conditions, a "bump" in frequency response of Electric Force Microscope (EFM) cantilevers may be observed, either in electrical amplitude or phase signals of AC gradients.…

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…

A 0-level packaged RF-MEMS switched wideband GaAs LNA MMIC

A. Gustafsson, C. Samuelsson, R. Malmqvist, S. Seok, M. Fryziel, N. Rolland, B. Grandchamp, T. Vähä-Heikkilä, R. Baggen

This paper focuses on the design of an RF-MEMS Dicke switched wideband LNA realized in a GaAs MMIC process that also includes a BCB cap type of wafer-level package. The 0- level packaged GaAs MEMS LNA circuit shows 10-17 dB of gain at 16-34 GHz when switched on. The off-state LNA gain is below -6…

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…

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…

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…

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…
