Second-order autoregressive model-based Kalman filter for the estimation of a slow fading channel described by the Clarke model: Optimal tuning and interpretation

Ali Houssam El Husseini, Eric Pierre Simon, Laurent Ros

This paper treats the estimation of a flat fading Rayleigh channel with Jakes' Doppler spectrum model and slow fading variations. A common method is to use a Kalman filter (KF) based on an auto-regressive model of order p (AR(p)). The parameters of the AR model can be simply tuned by using the…

Digital RF transmitter with single-bit ΔΣ M-driven switched-capacitor RF DAC and embedded band filter in 28-nm FD-SOI

Razvan-Cristian Marin, Antoine Frappé, Bruno Stefanelli, Philippe Cathelin, Andreia Cathelin, Andreas Kaiser

This paper presents a single-bit RF transmitter based on single-bit switched-capacitor RF digital-to-analog converters (DACs) embedded in an finite-impulse response (FIR) filter (FIR-DACs). The transmitter system comprises a single-bit quadrature delta-sigma modulator (M), a digital mixer, and a…

The Effects of AlN and Copper Back Side Deposition on the Performance of Etched Back GaN/Si HEMTs

Georges Pavlidis, Samuel Kim, Idriss Abid, Malek Zegaoui, F Medjdoub, Samuel Graham

The breakdown voltage of GaN/Si high electron mobility transistors (HEMTs) for power electronics has shown to be improved by removing the silicon substrate. The drawback to this approach is the increase in the device's thermal resistance which limits the power dissipation that the device can…

Toxicity Effect of Silver Nanoparticles on Photosynthetic Pigment Content, Growth, ROS Production and Ultrastructural Changes of Microalgae Chlorella vulgaris

Layla Hazeem, Gamze Kuku, Etienne Dewailly, Christian Slomianny, Alexandre Barras, Abderrahmane Hamdi, Rabah Boukherroub, Mustafa Culha, Mohamed Bououdina

Silver nanoparticles (Ag NPs) exhibit antibacterial activity and are extensively used in numerous applications. The aim of this study was to examine the toxic effect of Ag NPs on the marine microalga, Chlorella vulgaris. The microalgae, at the exponential growth phase, were treated with different…

Intrinsic transport properties of nanoporous graphene highly suitable for complementary field-effect transistors

Jing Li, Christophe Delerue

The recent success to synthesize an ordered array of pores in graphene by a bottom-up approach (Moreno et al 2018 Science 360 199) yields a semiconducting nanoporous graphene with a bandgap of 0.6 eV. In this paper, we present calculations of the intrinsic carrier mobility in this new type of two-…

Broadband vibrational energy harvesting with a spherical piezoelectric transducer devoted to underwater wireless sensor networks

Daher Diab, Nikolay Smagin, Fabrice Lefebvre, Georges Nassar, Samih Isber, Fawaz El Omar, Adnan Naja

A new sensing node container based on a spherical piezoelectric transducer is proposed. This device provides broadband vibrational energy harvesting and sensing facilities intended for underwater wireless sensor networks. The transducer is composed of two acrylic glass (PMMA) half-spherical shells…

Monitoring cleaning cycles of fouled ducts using ultrasonic coda wave interferometry (CWI)

Bowei Chen, Dorothée Debavelaere-Callens, Pierre Campistron, Emmanuel Moulin, Pascal Debreyne, Guillaume Delaplace

Fouling in heat exchangers is the buildup of deposits on the solid surfaces. These deposits reduce the eco-efficiency of the processing equipment and increase the risk of subsequent surface contamination with the formation of biofilms. In the agro-food and water supplier sectors, which are our main…
