Smart way to adjust Schottky barrier height in 130 nm BiCMOS process for sub-THz applications

Vincent Gidel, Frederic Gianesello, Pascal Chevalier, Gregory Avenier, Nicolas Guitard, Michel Buczko, Cyril Luxey, Guillaume Ducournau

In this paper, an innovative Schottky diode architecture is proposed and implemented in 130 nm BiCMOS technology. A state-of-the-art 1 THz cut-off frequency is measured and an innovative way to modify the height of the Schottky barrier is proposed. This smart way could enable zero-bias high-…

Frequency-domain simulation of power electronic systems based on multi-topology equivalent sources modelling method

Stephane Vienot, Arnaud Videt, Nadir Idir, Lamine Kone, Sebastien Weiss, Frederic Lafon

ElectroMagnetic Interference (EMI) simulation of power converters helps engineers in the design process. In this paper, we describe a frequency-domain simulation method based on the Multi-Topology Equivalent Sources (MTES) model. The aim is to reproduce the non-linear behavior of power switches for…

SVM Assisted Primary User-Detection for Non-Cooperative Cognitive Radio Networks

Kais Bouallegue, Matthieu Crussière, Sofiane Kharbech

This paper presents a new blind spectrum sensing (SS) algorithm based on a machine learning model: the radial basis function support-vector machines (RBF-SVM). As features, the introduced approach uses statistical tests that are based on the eigenvalues of the received signals covariance matrix.…

Robust Fano resonance in a topological mechanical beam

Wei Wang, Yabin Jin, Wan Wang, Bernard Bonello, Bahram Djafari-Rouhani, Romain Fleury

The advances in topological condensed matter physics enable the manipulation of classic waves in different ways, such as unidirectional propagation featuring the suppression of backscattering and the robustness against impurities and disorder, making it possible to endow classical phenomena with…

Investigation of resistive switching and transport mechanisms of Al ₂O₃/TiO_2−<i>x</i> memristors under cryogenic conditions (1.5 K)

Yann Beilliard, François Paquette, Frédéric Brousseau, Serge Ecoffey, F. Alibart, Dominique Drouin

Resistive switching and transport mechanisms of Al2O3/TiO2−x memristor crosspoint devices have been investigated at cryogenic temperatures down to 1.5 K, for the future development of memristor-based cryogenic electronics. We report successful resistive switching of our devices in the temperature…

LoS theoretical and experimental MIMO study from 1-40 GHz in indoor environments

Juan Pascual-Garcia, Maria-Teresa Martinez-Ingles, Davy Gaillot, Leandro Juan-Llacer, Jose-Maria Molina-Garcia-Pardo

In this work, line-of-sight multiple-input multiple-output (MIMO) measurements in the frequency range from 1 GHz to 40 GHz are presented for an indoor environment in the scope of new 5G bands. For the sake of comparison, the measured radio channels are reproduced with great accuracy using ray-…

Low-frequency noise parameter extraction method for single-layer graphene FETs

Nikolaos Mavredakis, Wei Wei, Emiliano Pallecchi, Dominique Vignaud, Henri Happy, Ramon Garcia Cortadella, Nathan Schaefer, Andrea Bonaccini Calia, Jose Antonio Garrido, David Jimenez

In this article, a detailed parameter extraction methodology is proposed for low-frequency noise (LFN) in single-layer (SL) graphene transistors (GFETs) based on a recently established compact LFN model. The drain current and LFN of two short channel back-gated GFETs (L = 300 and 100 nm) were…
