Forward V-band Vector Network Analyzer Based on a Modified Six-port Technique

Kamel Haddadi, Tuami Lasri

A V-band forward network analyzer based on a modified six-port technique is proposed for the measurement of complex reflection (S-11) and transmission (S-21) coefficients. The millimeter-wave part of the system is implemented on a thin alumina ceramic substrate. The measurement performance is...

When capacitive transduction meets the thermomechanical limit: Towards femto-newton force sensors at very high frequency

S. Houmadi, Bernard Legrand, J.P. Salvetat, B. Walter, E. Mairiaux, J.P. Aime, D. Ducatteau, P. Merzeau, L. Buisson, J. Elezgaray, Didier Theron, Marc Faucher

We show that the capacitive transduction of a MEMS device using a setup based on a microwave detection scheme achieves the measurement of the thermomechanical noise spectrum of a high-frequency (>10 MHz) high-stiffness (>10 5 N/m) resonator, reaching the outstanding displacement resolution of...

Semi-digital FIR DAC for low power single carrier IEEE 802.11ad 60GHz transmitter

Fikre Tsigabu Gebreyohannes, Antoine Frappé, Andreas Kaiser

IEEE 802.11ad (WiGig) is an emerging multi-Gb/s wireless standard in the unlicensed 60GHz spectrum. This work presents system level validation of a Single Carrier (SC), QPSK modulated WiGig transmitter based on a semi-digital Finite Impulse Response (FIR) Digital-to-Analog Converter (DAC). The 1....

Theoretical and experimental analyses of tunable Fabry-Perot resonators using piezoelectric phononic crystals

Marie-Fraise Ponge, Bertrand Dubus, Christian Granger, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

Theoretical and experimental analyses of piezoelectric stacks submitted to periodical electrical boundary conditions via electrodes are conducted. The presented structures exhibit Bragg band gaps that can be switched on or off by setting electrodes in short or open circuit. The band gap frequency...

Characterization of flexible CMOS technology tranferred onto a metallic foil

Justine Philippe, Aurelien Lecavelier Des Etangs-Levallois, Philip Latzel, Francois Danneville, J.F. Robillard, Daniel Gloria, Emmanuel Dubois

In this work we demonstrate a method to transfer high-performance industrial CMOS circuits thinned down to 5.7 mu m and bond onto a 25-mu m-thick stainless steel foil with a 800-nm-thick indium layer. The bonding is performed at the temperature of 100 degrees C with an applied pressure of 1.2 bar....

Modeling of ZigBee (IEEE 802.15.4) channel in rail environment for Intelligent Transport

Ulrich Biaou, Laïd Sadoudi, Michael Bocquet, Atika Rivenq

To deploy Wireless Sensor Networks (WSNs) in the railway transport, knowledge of signal propagation in this environment is required for the safety and the reliability of whole system. This calls to two domains of research. Firstly, the study of the propagation characteristics is necessary to...
