In this paper we analyze the impact of CMOS technology scaling on power consumption of UWB impulse radios. It is shown that the power consumption of the synchronization constitutes a large portion of the total power in the receiver. A traditional technique to reduce the power consumption at the receiver is to operate the UWB radios with a very low duty cycle on an architecture with extreme parallelism. On the other hand this requires more silicon area and this is limited by the leakage power consumption which becomes more and more a problem in future CMOS technologies. The proposed quantitative framework allows systematic use of digital low-power design techniques in future UWB transceivers. Copyright 2006 Mustafa Badaroglu et al.

INTRODUCTION UWB impulse radios are good candidates for low-power radios in sensor networks 1 . They offer lower power communication due to higher levels of integration and duty cycling and the ability to do ranging 2 . In this paper we focus on power consumption aspects of integrated UWB impulse radios. One possible solution to
