Experimental Study and Device Design of NO, NO2, and NH3 Gas Detection for a Wide Dynamic and Large Temperature Range Using Pt/AlGaN/GaN HEMT

Chris Bishop, Yacine Halfaya, Ali Soltani, Suresh Sundaram, Xin Li, Jérémy Streque, Youssef El Gmili, Paul B Voss, Jean-Paul Salvestrini, Abdallah Ougazzaden

We report an AlGaN/GaN HEMT gas sensor designed to enable NO, NO2, and NH3 detection from 100°C-400°C over a large concentration range. Device modeling is performed to optimize several HEMT device parameters for sensing, and the experimental results show that the optimized sensor has improved...

Improved Cluster-tree Topology Adapted for Indoor environement in Zigbee Sensor Network

Mourad Ouadou, Ouadoudi Zytoune, Driss Aboutajdine, Yassin El Hillali, Atika Rivenq

Wireless Sensor Network (WSN) is a collection of small sensor nodes with aptitude to sense, compute and transmit data that are deployed to observe a physical environment. The sensor node has limited capabilities, especially for energy reserve and memory storage, that is why topology and routing...

Contact resistance study of “edge-contacted” metal-graphene interfaces

V. Passi, A. Gahoi, J. Ruhkopf, S. Kataria, Francois Vaurette, E. Pallecchi, H. Happy, M. C. Lemme

The contact resistance RC of "edge-contacted" metal-graphene interfaces is systematically studied. Our experiments demonstrate a reduction of contact resistance by intentional patterning of graphene to create "edge contacts". The parameter space for different hole patterns in...

Personal radio-frequency exposimeters in indoor diffuse environments: Measurement and simulation

Reza Aminzadeh, Arno Thielens, Aliou Bamba, Lamine Kone, Davy Gaillot, M. Lienard, Luc Martens, Wout Joseph

The response of personal exposimeters (PEMs) is studied under diffuse field exposure in indoor environments. A numerical model and a setup for on-body calibration measurements in a reverberation chamber (RC) is proposed for 897–5500 MHz. The proposed numerical simulations are in good agreement with...

Deep Trench Isolation and Through Silicon Via Wetting Characterization by High-Frequency Acoustic Reflectometry

Christophe Virgilio, Lucile Broussous, Philippe Garnier, Julien Carlier, Pierre Campistron, V. Thomy, Malika Toubal, Pascal Besson, Laurence Gabette, Bertrand Nongaillard

Wetting efficiency of microstructures or nanostructures patterned on Si wafers is a real concern in integrated circuits manufacturing. We present here a high-frequency acoustic method which enables the local determination of the wetting state of a liquid on real DTI and TSV structures. Partial...

65 nm SOI CMOS 60 GHz passive mixer for six-port technology

Kamel Haddadi, Christophe Loyez

This work describes the design and measurements of a 60 GHz passive mixer for six-port applications operating and implemented in a 65nm SOI CMOS technology. The mixer topology, consisting only of a n-MOS cold-FET and CPW transmission line matching networks, avoids the use of coupler in front of the...

A co-design space exploration tool for avionic high performance heterogeneous embedded architectures

Geoffroy Pertuisot, Nicolas Belanger, Yassin El Hillali, Smail Niar, Atika Rivenq

Avionics in the helicopter manufacturers' landscape faces new challenges. Whereas customers raise continuously their needs in terms of new functions and embedded systems performances, certification authorities maintain complex rules to fulfill for parallel computing. This constraining...

Modeling transistor level masking of soft errors in combinational circuits

Ihsen Alouani, Smail Niar, Yassin El Hillali, Atika Rivenq

Technology scaling in modern electronic circuits shrinks the transistor size and dramatically increases the sensitivity of semiconductor devices to radiations. Consequently, soft errors emerged as a serious reliability threat in both sequential and combinational circuits. To accurately estimate...
