AIDX: Adaptive Inference Scheme to Mitigate State-Drift in Memristive VMM Accelerators

Tony Liu, Amirali Amirsoleimani, F. Alibart, Serge Ecoffey, Dominique Drouin, Roman Genov

An adaptive inference method for crossbar (AIDX) is presented based on an optimization scheme for adjusting the duration and amplitude of input voltage pulses. AIDX minimizes the long-term effects of memristance drift on artificial neural network accuracy. The sub-threshold behavior of memristor…

Low impedance and highly transparent microelectrode arrays (MEA) for in vitro neuron electrical activity probing

Anna Susloparova, Sophie Halliez, Séverine Begard, Morvane Colin, Luc Buée, Sébastien Pecqueur, F. Alibart, V. Thomy, S. Arscott, Emiliano Pallecchi, Yannick Coffinier

In this study, we present the microfabrication and characterization of a transparent microelectrode array (MEA) system based on PEDOT:PSS for electrophysiology. The influence of the PEDOT:PSS electrode dimensions on the impedance was investigated and the stability over time under physiological…

Angular characteristics of multipath propagation in an indoor industrial environment

Aliou Bamba, Emmeric Tanghe, Aladji Kamagate, Pierre Laly, Frederic Challita, Adama Konate, Wout Joseph, M. Lienard, Davy Gaillot

The characteristics of multipath components (MPCs) are addressed in an industrial environment at 1.3 GHz by means of measurements with a multidimensional channel sounder. The maximum likelihood estimator, RiMAX, is used to determine the MPCs parameters and takes into account the diffuse scattering…

High temperature gradient micro-sensors for skin-friction measurement in flow control applications

Cécile Ghouila-Houri, Manon Benedito, Eric Garnier, Abdelkrim Talbi, Aurélien Mazzamurro, Romain Viard, Alain Merlen, Philippe Pernod, Thomas Arnoult, Quentin Gallas

Robust micro machined high temperature gradient calorimetric (HTGC) transducers were designed and developed for flow separation control. Based on thermal principle, the transducers measure the amplitude and the sign of skin friction, making them particularly useful for flow separation detection. A…

Experimental and theoretical study of group delay times and density of states in one-dimensional photonic circuit

S. Khattou, M. Amrani, A. Mouadili, E.H. El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

We present a comparative study of density of states (DOS) and group delay times for a one-dimensional (1D) coaxial photonic crystal made of N cells attached horizontally along a waveguide. Using the interface response theory of continuous media, we derive exact analytical expressions relating the…

Event-Driven Continuous-Time Feature Extraction for Ultra Low-Power Audio Keyword Spotting

S. Mourrane, Benoit Larras, A. Cathelin, Antoine Frappé

In the context of autonomous keyword spotting and sound detection, this paper proposes a low power feature extraction unit generating spectrograms that represent a unique signature allowing the classification of audio signals. This system is composed of a continuous-Time digital signal processing…
