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…

Hydrothermal preparation of MoS₂/TiO₂/Si nanowires composite with enhanced photocatalytic performance under visible light

A. Hamdi, L. Boussekey, P. Roussel, A. Addad, H. Ezzaouia, Rabah Boukherroub, Yannick Coffinier

In this paper, we report on a simple, low cost and environmentally friendly method for the synthesis of 3D hierarchical molybdenum disulfide (MoS₂) nano-sheets on TiO₂ coated Si nanowires (SiNW). The synthetic method has several advantages such as low…

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…

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.…

Porous Gold Films Fabricated by Wet-Chemistry Processes

Aymeric Pastre, Odile Cristini, Alexandre Boé, Katarzyna Raulin, Bertrand Grimbert, Fernand Chassagneux, Nathalie Rolland, Remy Bernard

Porous gold films presented in this paper are formed by combining gold electroless deposition and polystyrene beads templating methods. This original approach allows the formation of conductive films (2 × 106 (Ω·cm)−1) with tailored and interconnected porosity. The porous gold film was deposited up…

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…
