Ultra low power analog design and technology for artificial neurons

Francois Danneville, Ilias Sourikopoulos, Sara Hedayat, Christophe Loyez, Virginie Hoel, A. Cappy

In a context of the end of Moore's law, energy dissipation constitutes a real challenge. Among the new energy efficient paradigms for data processing, bio-inspired computing is very promising, moreover introducing cognitive characteristics. As applications at very high scale are addressed, the…

Luminescence imaging of photoelectron spin precession during drift in a p-type GaAs microfabricated Hall bar

V. Notot, D. Paget, A. Rowe, L. Martinelli, Fabian Cadiz, S. Arscott

Using a microfabricated p-type GaAs Hall bar, it is shown that the combined application of co-planar electric and magnetic fields enables the observation of spatial oscillations of the photoluminescence circular polarization due to the precession of drifting spin-polarized photoelectrons.…

Tuning the Cation Ordering with the Deposition Pressure in Sputtered LiMn1.5Ni0.5O4 Thin Film Deposited on Functional Current Collectors for Li-Ion Microbattery Applications

Manon Létiche, Maxime Hallot, Marielle Huve, Thierry Brousse, Pascal Roussel, C. Lethien

The development of high voltage spinel LiMn1.5Ni0.5O4 (LMNO) sputtered thin films on functional current collector was reported within the framework of this study. We have first solved the technological issue due to the PtSi phase which originates from the interdiffusion between silicon wafer and…

Experimental investigation of the lateral resolution of a homemade near field microwave microscope

Tianjun Lin, S. Gu, T. Lasri

In this paper an experimental investigation of the lateral resolution of a homemade near field microwave microscope (NFMM) is reported. The optimal lateral resolution is studied by a thorough analysis of the influence of critical parameters such as the stand-off distance, the tip apex size and the…

Energy Efficient Hardware and Improved Cluster-Tree Topology for Lifetime Prolongation in ZigBee Sensor Networks

Mourad Ouadou, Ouadoudi Zytoune, Yassin El Hillali, Atika Rivenq, Driss Aboutajdine

In wireless sensor networks, building energy-efficient systems is one of the major challenges. In such networks, nodes are usually supplied by low power and small batteries. Many factors are involved in the energy consumption, and this issue may be considered as a cross-layer problem, from the…

Coupling of two resonant modes for insect wing mimicking in a flexible-wing NAV and generate lift

Damien Faux, Eric Cattan, Sébastien Grondel, Olivier Thomas

This work is based on the original concept of coupling two resonant vibration modes to reproduce insect wing kinematics and generate lift. The key issue is designing the geometry and the elastic properties of the artificial wings to achieve quadrature coupling of the bending and twisting motions…

Combined scanning microwave and electron microscopy: a novel toolbox for hybrid nanoscale material analysis

Kamel Haddadi, O. C. Haenssler, K. Daffe, S. Eliet, Christophe Boyaval, Didier Theron, Gilles Dambrine

A novel toolbox for hybrid nanoscale material characterization is presented. The system consists of a nano-robotic, compact and modular near-field scanning microwave microscope (NSMM) integrated into a high resolution scanning electron microscope (SEM). The instrument developed can perform hybrid…

A 65-nm CMOS 7fJ per synaptic event clique-based neural network in scalable architecture

Benoit Larras, Paul Chollet, Cyril Lahuec, Fabrice Seguin, Matthieu Arzel

Clique-based neural networks are less complex than commonly used neural network models. They have a limited connectivity and are composed of simple functions. They are thus adapted to implement neuro-inspired computation units operating under severe energy constraints. This paper shows an ST 65-nm…
