50 Shades of Delta Sigma

Chadi Jabbour, Antoine Frappé, Nicolas Schlegel

Delta Sigma modulators (DSM) have been around for more than 60 years. In 1962, Inose and his colleagues introduced one of the first implementations of DSM for a code modulation communication for a telemetering system. Since, during more than 6 decades, this remarkable architecture was employed to...

An In-Cell Weight Update Scheme Using One-Hot Gradients for On-Chip Learning

Mathieu Chêne, Benoit Larras, Andreas Kaiser, Antoine Frappé

In the context of edge AI, the embedded models need to be retrained on-chip. The more the backward path and the calculation the gradient (two important steps during learning) are optimized by literature, the more it becomes interesting to optimize weight update operation. This work proposes to...

All-Microwave on-off Keying Modulation Based on Multifunctional Metasurfaces

Ashif Aminulloh Fathnan, Taufiqqurrachman Taufiq, Fadil Habibie Danufane, Iyad Dayoub

<div><p>We introduce a novel on-off keying (OOK) modulator utilizing nonlinear multifunctional metasurfaces to transfer information between different frequency microwave signals. The metasurface absorbs microwave signals with lower frequency that initially carries information but...

Two-dimensional materials (2DMs) offer unique properties primarily due to their crystallographic structure, which consists of weakly coupled layers composed of one to few atomic planes where the atoms are covalently bonded. This specific structure results in the absence of dangling bonds at the..., Les matériaux bidimensionnels (2MDs) offrent des propriétés uniques principalement dues à leur structure cristallographique, composée de couches faiblement couplées constituées d'un à quelques plans atomiques où les atomes sont liés de manière covalente.

Imagerie non linéaire par ondes de Lamb de défauts d'impact dans des plaques en composite stratifié

Pierre Goislot, Guillemette Ribay, Emmanuel Moulin, Lynda Chehami

Les matériaux composites sont de plus en plus utilisés dans l'industrie aéronautique. Des impacts de faible énergie peuvent survenir en vol ou lors de la maintenance, provoquant des dommages invisibles à l'oeil nu mais qui fragilisent considérablement la structure. Cette thèse s'est...
