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...

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....

Eve, you shall not get access! A cyber-physical blockchain architecture for electronic toll collection security

Ahmed Didouh, Anthony Bahadir Lopez, Yassin El Hillali, Atika Rivenq, Mohammad Abdullah Al Faruque

Cooperative intelligent transportation system (C-ITS) applications are generally susceptible to position spoofing-dependent attacks such as Sybil and DDoS attacks due to a lack of established solutions. This paper presents a novel cyber-physical blockchain cryptographic architecture to help prevent...
