Sommario/riassunto

This book investigates the possible circuit solutions to overcome the temperature- and supply voltage-sensitivity of fully-integrated time references for ultra-low-power communication in wireless sensor networks. The authors provide an elaborate theoretical introduction and literature study to enable full understanding of the design challenges and shortcomings of current oscillator implementations.  Furthermore, a closer look to the short-term as well as the long-term frequency stability of integrated oscillators is taken. Next, a design strategy is developed and applied to 5 different



oscillator topologies and 1 sensor interface.All 6 implementations are subject to an elaborate study of frequency stability, phase noise, and power consumption. In the final chapter all blocks are compared to the state of the art. The main goals of this book are: • to provide a comprehensive overview of timing issues and solutions in wireless sensor networks; • to gain understanding of all underlying mechanisms by starting from the oscillator basics; • to provide and demonstrate a design strategy by describing the development of 6 state of the art process-, temperature- and supply voltage- independent building blocks and discussing the design trade-offs; • to demonstrate the reliability and functionality of the developed building blocks by integrating them in a complete, autonomous, flexible wireless tag; • to be a reference work for beginners as well as more experienced oscillator and ultra-low-power circuit design engineers.  .

Sommario/riassunto

Depuis l’avènement des droits de l’homme sur la scène internationale, la fameuse règle dite de la continuité de la nationalité mérite plus que jamais les critiques qui, dès son apparition, n’ont pas manqué de lui être adressées. Partant de la distinction fondamentale entre continuité



de la nationalité proprement dite et continuité de l’identité du titulaire du droit fondant la réclamation internationale, l’auteur procède à une analyse approfondie de la pratique internationale. Celle-ci démontre que la règle en question fait aujourd’hui encore partie du droit positif, en dépit des réactions aux nombreuses injustices engendrées par son application.  C’est par un examen des circonstances entourant l’apparition de la règle, en particulier du contexte de la protection diplomatique, qu’il devient possible de comprendre comment on en est venu à adopter et généraliser un principe constamment remis en question.  L’ouvrage offre enfin une réflexion critique portant sur la protection diplomatique elle-même, ainsi que sur les théories qui tentent d’en expliquer les fondements. Grâce à un éclairage neuf, il analyse de façon rigoureuse les rapports de droit complexes unissant l’étranger lésé, son Etat national et l’Etat dont la responsabilité internationale se trouve engagée.
