Book
Distortion analysis of analog integrated circuits
Piet Wambacq,Willy Sansen +1 more
TL;DR: General techniques to suppress nonlinear behavior such as pre-distortion, linear and nonlinear feedback are explained in detail and illustrated with realistic examples to fill the gap between the theory of nonlinear systems and practical analog integrated circuits.
Journal ArticleDOI
Ultra-wideband channel model for communication around the human body
TL;DR: A simple statistical channel model is proposed and a practical implementation useful for evaluating UWB body area communication systems is proposed.
Journal ArticleDOI
An ultra-wideband body area propagation channel Model-from statistics to implementation
TL;DR: It is found that components diffracting around the body are well modeled using correlated log normal variables, and a Nakagami-m distribution can be used to incorporate the influence of arm motions.
Journal ArticleDOI
Ultra-wide-band transmitter for low-power wireless body area networks: design and evaluation
Julien Ryckaert,Claude Desset,A. Fort,Mustafa Badaroglu,V. De Heyn,Piet Wambacq,G. Van der Plas,Stéphane Donnay,B. Van Poucke,Bert Gyselinckx +9 more
TL;DR: It is shown that UWB performs better in the short range due to a reduced baseline power consumption, and the very little hardware complexity of a UWB transmitter offers the potential for low-cost and highly integrated solutions.
Journal ArticleDOI
Symbolic analysis methods and applications for analog circuits: a tutorial overview
TL;DR: The history and present state of the art in symbolic analysis of electronic circuits at the so-called circuit level is given, and algorithmic details are provided for symbolic approximation, hierarchical decomposition, and symbolic distortion analysis.
