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…

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…

A multi-tone high efficient bandwidth system with an eliminated even-order distortions using double dual-parallel Mach-Zehnder modulator

Taimur Mirza, Shyqyri Haxha, Iyad Dayoub

In this paper, a linearization of dual RF channels over a single carrier wavelength is proposed and experimentally demonstrated. Multiple microwave signals with a multi-octave bandwidth are modulated by a double dual-parallel Mach-Zehnder modulator (D-DPMZM) and recovered by a differential balanced…

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…

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…

The specific properties of closed loop eigenfunctions deserve to be better understood. This chapter underlines that responses in closed loops differ from the responses in open loops. Within the following simple examples, constructed on closed loop robust zeros, many path states are found.A robust…

6 - Closed loop and stubs

L. Dobrzynski, Housni Al Wahsh, Abdellatif Akjouj, Cécile Ghouila-Houri, Abdelkrim Talbi, Gaëtan Lévêque, El Houssaine El Boudouti

Closed loops with finite open loops attached to the robust zeros of one of their two twin states are the systems investigated in this chapter. Such attached finite loops are called stubs. For simplicity, here only the cases where all the stubs have the same length are considered. This length is…

4 - Open loop examples

Housni Al Wahsh, L. Dobrzynski, Abdellatif Akjouj, El Houssaine El Boudouti

The simplest general robust zero is the middle of an open loop. When the middles of several free-end open loops of the same length are superposed, their antisymmetric eigenfunctions remain unperturbed and the final network has several degenerate states. The next three examples take into account…
