Abstract :
|
In this paper we discuss the design issues of an
Ultra Wide Band (UWB) receiver, targeting a single-chip CMOS
implementation for low data-rate applications like {\em ad hoc}
wireless sensor networks. A non-coherent transmitted-reference
(TR) receiver is chosen because of its small complexity compared
to other architectures. Issues, challenges and possible design
solutions are discussed. In particular, an analysis of the
trade-off between performance and complexity in an integrated
circuit implementation is given.
