Millimeter-wave six-port IQ demodulator in 65 nm SOI CMOS technology

Kamel Haddadi, Christophe Loyez

This work describes a 65 nm SOI CMOS passive mixer architecture consisting of a n-MOS cold-FET and coplanar waveguide (CPW) transmission line matching networks for six-port IQ demodulation of millimeter-wave signals. The circuit architecture avoids the use of coupler in front of the detection…

Investigation of the performance of HEMT based NO, NO2 and NH3 exhaust Gas Sensors for Automotive Antipollution Systems

Yacine Halfaya, Chris Bishop, Ali Soltani, Sundaram Suresh, Vincent Aubry, Paul L. Voss, Jean-Paul Salvestrini, Abdallah Ougazzaden

We report improved sensitivity to NO, NO2 and NH3 gas with specially-designed AlGaN/GaN high electron mobility transistors (HEMT) that are suitable for operation in the harsh environment of diesel exhaust systems. The gate of the HEMT device is functionalized using a Pt catalyst for gas detection.…

Delta-sigma based digital transmitters with low-complexity embedded-FIR digital to RF mixing

Razvan-Cristian Marin, Antoine Frappé, Andreas Kaiser

The focus of this contribution is to review delta-sigma based all-digital transmitters and to discuss issues related to large out-of-band quantization noise and possible coexistence problems. Low-complexity embedded-FIR filters are very interesting to relax the filtering constraints while keeping…

Length dependence of thermal conductivity by approach-to-equilibrium molecular dynamics

Hayat Zaoui, Pier Luca Palla, Fabrizio Cleri, Évelyne Martin

The length dependence of thermal conductivity over more than two orders of magnitude has been systematically studied for a range of materials, interatomic potentials, and temperatures using the atomistic approach-to-equilibrium molecular dynamics (AEMD) method. By comparing the values of…

SAW synthesis with IDTs array and the inverse filter: toward a versatile SAW toolbox for microfluidics and biological applications

Antoine Riaud, Michael Baudoin, Jean-Louis Thomas, Olivier Bou Matar

Surface acoustic waves (SAWs) are versatile tools to manipulate fluids at small scales for microfluidics and biological applications. A non-exhaustive list of operations that can be performed with SAW includes sessile droplet displacement, atomization, division and merging but also the actuation of…

Modeling of Fermi-level pinning alleviation with MIS contacts: n and pMOSFETs cointegration considerations-Part I

Julien Borrel, Louis Hutin, Olivier Rozeau, Marie-Anne Jaud, Sebastien Martinie, Magali Gregoire, Emmanuel Dubois, Maud Vinet

Aiming at overcoming the Fermi-level pinning (FLP) occurring at the metal/semiconductor interfaces, metal/insulator/semiconductor (MIS) contacts to n-Si and p-Si are usually treated in separate optimization studies, yet with no particular insight on their technological compatibility. In this paper…
