The successful realization of a Wireless Body Area Network (WBAN) requires innovative solutions to meet the energy consumption budget of the autonomous sensor nodes. The radio interface is a major challenge, since its power consumption must be reduced below 100μW (energy scavenging limit). The emerging Ultra-WideBand (UWB) technology shows strong advantages(More)
Wireless communication systems enable new and exciting applications, but also impose significant technical challenges to achieve the required performance at minimal energy consumption. Traditionally, those systems are designed and optimized for operation in one typical situation, taking into account some worst case considerations and a functional layer(More)
Impulse-based Ultra-Wideband systems are appealing for low-power short-range communications as they can benefit from duty-cycled low-complexity analog architectures. Low-power receivers correlate in the analog domain and sample only at the pulse repetition frequency. However, achieving acquisition with such a receiver requires an efficient search strategy,(More)
Ultra-wideband (UWB) impulse radios show strong advantages for the implementation of low-power transceivers. 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(More)
