Pulmonary arterial hypertension (PAH) is a rare, progressive cardiovascular disease that affects an average of 15 to 50 individuals per 1 million worldwide. It is characterized by an abnormal rise in pressure in the pulmonary arteries, which can lead to severe right heart failure, and Biomedical research on cardiovascular diseases heavily relies on...
L'ischémie cardiaque est une pathologie cardiaque qui est, selon l'Organisation Mondiale de la Santé, la première cause de mortalité. Il s'agit d'une vascularisation insuffisante des cellules du myocarde qui, si elle perdure, entraîne un infarctus cardiaque, c'est-à-dire la nécrose d'une partie du cœur, et met en danger la vie du patient. Néanmoins...
L'introduction de la 5G et l'amélioration des débits de données ont entraîné le déploiement de nouvelles plages de fréquences, notamment autour de 30 GHz, ce qui a réduit la portée des signaux. Pour remédier à cette limitation, le beamforming est une solution qui consiste à combiner divers faisceaux de signaux à l'aide des antennes d'émission situé...
The THz part of the spectrum allows disruptive applications such as 100 Gb/s wireless communications, imaging, spectroscopy and offers an interesting perspective for the 6G future standards. The need for this kind of applications is rising and nanoscale VLSI CMOS technologies dispose of active devices with high enough ft and fmax to integrate Syste...
Over the past decade, there has been increasing interest in ambient energy harvesting to provide an autonomous power source for low-power wireless sensors which are used in a variety of applications. This overcomes the problems associated with the need for frequent battery replacement or recharging, especially when wireless sensors are deployed on ...

Integrated circuit (IC) test is a key technical part of IC chain, which works through the entire life cycle of IC design, manufacturing, packaging, and application. Based on the increasing requirements of IC test, this paper analyzes the breakthrough point to promote the development of IC test and puts forward an accurate and feasible programme of ...
This paper presents a comparative performance analysis of LNAs realized in GaAs and GaN/Si technologies in the context of 5G mmWave massive MIMO transceiver. Regardless the choice of architecture for beamforming, a key component of the base station transmitter is the RF frontend. In this paper, we investigate the linear and nonlinear performance in...
[ES] El presente proyecto plantea, en el ámbito del diseño digital y la verificación funcional, un sistema de automatización de regresiones. Existe un repositorio compartido donde se suben tanto los ficheros de diseño digital (Hardware Description Language, HDL) como los ficheros de verificación. Los ficheros en el repositorio deben ser correctos e...
This paper presents a comparative performance analysis of two LNAs realized in GaAs and GaN technologies for millimeter wave T/R chip (transceiver/receiver) applications. Circuits are fabricated using two different technologies and characterized on board. Measurements are performed in 24–32 GHz frequency band. A first comparison based on classic me...
This paper describes a fast methodology for managing the obsolescence issues of integrated circuits in industrial equipment (aeronautical or automotive). The objective is to predict EMC non-compliance risk, especially for conducted immunity, after a component change. Based on black box modeling using S-parameters, this experimental approach consist...
