A Theoretical Analysis of the Frequency Response in p-i-n Photodiodes that Use InGaAs/InP Materials

Nesrine Bakalem, Abdelkader Aissat, Samuel Dupont, Faouzi Saidi, Mohamed Houcine Dhaou, Jean Pierre Vilcot

This investigation is centered on the analysis of frequency response characteristics of a p-i-n photodiode using InxGa$_{1-x}$As/InP. The InGaAs/InP can be developed under three conditions: compression, tensile strain, and lattice matching. Initially, we performed calculations on strain, bandgap…

Boosting hyperspectral image classification with Gate-Shift-Fuse mechanisms in a novel CNN-Transformer approach

Mohamed Fadhlallah Guerri, Cosimo Distante, Paolo Spagnolo, Abdelmalik Taleb-Ahmed

Hyperspectral Image (HSI) classification categorizes every pixel sample into distinct land-cover types. While CNN-based methods have demonstrated significant advances in feature representation, they often struggle with extracting deep features. On the other hand, transformer models excel in…

PE-CLIP: A Parameter-Efficient Fine-Tuning of Vision Language Models for Dynamic Facial Expression Recognition

Ibtissam Saadi, Abdenour Hadid, Douglas Cunningham, Abdelmalik Taleb-Ahmed, Yassin El Hillali

Vision-Language Models (VLMs) like CLIP offer promising solutions for Dynamic Facial Expression Recognition (DFER) but face challenges such as inefficient full fine-tuning, high complexity, and poor alignment between textual and visual representations. Additionally, existing methods struggle with…

A Sub-400-nW Real-Time Event-Driven Spectrogram Extraction Unit in 28-nm FD-SOI CMOS for Keyword Spotting Application

Soufiane Mourrane, Benoit Larras, Sylvain Clerc, Andreia Cathelin, Antoine Frappé

Considering the power-hungry nature of speech processing, a keyword spotting (KWS) unit, used to detect multiple spoken words, is often integrated as a front-end layer. KWS systems are always active, and thus, it is extremely important to optimize the devoted power budget. In this context, this…

Imagerie passive de couches sur substrats par corrélation de champ acoustique haute fréquence

Nada Ben Jafela, Lynda Chehami, Marc Duquennoy, Emmanuel Moulin, Nikolay Smagin, Dame Fall, Zakariae Oumekloul

Les structures couche sur substrat sont généralement sujettes à divers types de défauts, en particulier ceux liés au processus de fabrication lors de la croissance des films minces. Actuellement, une possibilité pour inspecter ces structures consiste à utiliser des transducteurs IDTs en émission et…

Inverted BER Trends for Energy-Detected GRSM-MQAM Massive MIMO Downlink

Oshin Daoud, Haïfa Farès, Yahia Medjahdi, Laurent Clavier, Amor Nafkha

This work investigates Generalized Receiver Spatial Modulation (GRSM) in a massive MIMO downlink scenario over millimetre wave channels. While GRSM enhances spectral efficiency (SE) and reduces power consumption, indexing additional bits using the spatial dimension increases the vulnerability to…
