Le concept d\u2019Human Intranet vise \u00e0 interconnecter diff\u00e9rents types de capteurs et d\u2019actionneurs sur le corps humain pour des applications m\u00e9dicales et bien-\u00eatre. Les solutions RF connues, telles que le Bluetooth ou l\u2019Ultra-Wideband, subissent l&rsquo;effet d&rsquo;ombre du corps, qui d\u00e9grade la qualit\u00e9 et la fiabilit\u00e9 du canal de communication. Comme alternative, la communication coupl\u00e9e au corps humain, o\u00f9 le corps humain est utilis\u00e9 comme moyen de propagation, a \u00e9t\u00e9 \u00e9tudi\u00e9e. Les communications coupl\u00e9es au corps humain n\u00e9cessitent des \u00e9metteurs-r\u00e9cepteurs avec un d\u00e9bit de donn\u00e9es flexible, une exp\u00e9rience utilisateur confortable, une faible consommation d\u2019\u00e9nergie, une couverture de communication \u00e9lev\u00e9e et une grande robustesse.

L\u2019\u00e9metteur fonctionne \u00e0 450 MHz o\u00f9 la propagation par ondes de surface est le m\u00e9canisme dominant, offrant une plus grande largeur de bande avec un canal de communication plus stable. L\u2019\u00e9metteur \u00e0 rapport-cyclique \u00e9lev\u00e9 utilise un oscillateur en anneau pseudo-diff\u00e9rentiel de 90 MHz en boucle ouverte et des combinateurs de fronts pour g\u00e9n\u00e9rer des impulsions modul\u00e9es en OOK de forme gaussienne \u00e0 travers un amplificateur de puissance \u00e0 capacit\u00e9s commut\u00e9es (SCPA).

The Human Intranet concept aims at interconnecting different types of sensors and actuators on the human body for medical and wellness applications. Known RF solutions, such as Bluetooth or Ultra-Wideband, suffer from the shadow effect of the body, which degrades the quality and reliability of the communication channel. As an alternative, body-coupled communication, where the human body is used as a propagation medium, has been studied. Human body coupled communication requires transceivers with flexible data rate, comfortable user experience, low power consumption, high communication coverage and high robustness. This thesis presents an all-digital pulse-based transmitter for capacitive human body-coupled communications(c-BCC) in 28 nm FD-SOI CMOS technology. The transmitter operates at 450 MHz where surface wave propagation is the dominant mechanism, providing greater bandwidth with a more stable communication channel. The high-ratio transmitter uses a 90 MHz open-loop pseudo-differential ring oscillator and edge combiners to generate Gaussian-shaped OOK-modulated pulses through a switched capacitor power amplifier (SCPA). The wide substrate bias voltage range offered by FD-SOI technology allows for frequency tuning and efficiency optimization based on data rate. The proposed transmitter consumes 17-76 \u03bcW for flexible data rates of 0.1-27 Mb\/s (170 pJ\/b to 2.8 pJ\/b) with a system efficiency of up to 14% at a supply voltage of 0.5 V. This work also presents a methodology for designing ultra-low voltage SCPAs in 28 nm FD-SOI CMOS, as well as design considerations for ultra-low power receivers.<\/p>\n<\/div><\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"author":20,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[316],"tags":[],"class_list":["post-55377","post","type-post","status-publish","format-standard","hentry","category-theses-2022"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/55377","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=55377"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/55377\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=55377"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=55377"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=55377"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
