A generalized deep learning-based framework for assistance to the human malaria diagnosis from microscopic images

Ziheng Yang, Halim Benhabiles, Karim Hammoudi, Feryal Windal, Ruiwen He, Dominique Collard

Malaria is an infectious disease caused by Plasmodium parasites and is potentially human life-threatening. Children under 5 years old are the most vulnerable group with approximately one death every two minutes, accounting for more than 65% of all malaria deaths. The World Health Organization (WHO…

Non-linear analysis of a broadband power amplifier at 300 GHz

Haitham Ghanem, Benjamin Schoch, Ingmar Kallfass, P. Szriftgiser, Malek Zegaoui, Mohammed Zaknoune, Francois Danneville, Guillaume Ducournau

In this article we present a new method to measure the third-order intercept point (IP3) of a 300 GHz medium power amplifier MMIC based on III-V technology in an on-wafer measurement setup. The extraction was carried out using a uni-travelling carrier photodiode as the input signal source. Taking…

Back gate impact on the noise performances of 22FDX fully-depleted SOI CMOS

Ousmane Magatte Kane, Luca Lucci, Pascal Scheiblin, Thierry Poiroux, Jean-Charles Barbé, Francois Danneville

Ultra-Thin-Body and Back-oxide Fully-Depleted Silicon-On-Insulator (UTBB-FDSOI) MOSFETs are the most recent and advanced Silicon-On-Insulator (SOI) architecture proposed to overcome the down-scaling limitations of traditional bulk devices. The UTBB-FDSOI architecture has already been proved very…

High-Q silicon nitride drum resonators strongly coupled to gates

Xin Zhou, Srisaran Venkatachalam, Ronghua Zhou, Hao Xu, Alok Pokharel, Andrew Fefferman, Mohammed Zaknoune, Eddy Collin

Silicon nitride (SiN) mechanical resonators with high quality mechanical properties are attractive for fundamental research and applications. However, it is challenging to maintain these mechanical properties while achieving strong coupling to an electrical circuit for efficient on-chip integration…

Development of broadband high-frequency piezoelectric micromachined ultrasonic transducer array

Xu-Bo Wang, Le-Ming He, You-Cao Ma, Wen-Juan Liu, Wei-Jiang Xu, Jun-Yan Ren, Antoine Riaud, Jia Zhou

Piezoelectric micromachined ultrasonic transducers (PMUT) are promising elements to fabricate a two-dimensional (2D) array with a pitch small enough (approximately half wavelength) to form and receive arbitrary acoustic beams for medical imaging. However, PMUT arrays have so far failed to combine…

Growth temperature effect on physical and mechanical properties of nitrogen rich InN epilayers

Z. Benzarti, T. Sekrafi, A. Khalfallah, Zahia Bougrioua, D. Vignaud, M. Evaristo, A. Cavaleiro

A set of N-polar InN epilayers has been grown at different temperatures by plasma-assisted molecular beam epitaxy (PA-MBE) on GaN/AlN/Al2O3(0001) templates. The purpose is to understand how the variation of crucial factor, such as the temperature, impacts the growth process and the resulting…

Bowl-shaped ZnO ultrasonic transducer for photoacoustic/ultrasonic multimode microscopy

J. Zhang, D. Zhao, D. Li, F. Tian, Wei-Jiang Xu, X. Wu

A bowl-shaped ultrasonic transducer is proposed for photoacoustic/ultrasonic multimode microscopy. The transducer uses zinc oxide (ZnO) as the piezoelectric material, which has a better electromechanical coefficient than flexible PVDF polymer and ensures the detection sensitivity. The ZnO film is…
