A study of low-power ultra wideband radio transceiver architectures

The paper studies low-power ultra wideband (UWB) transceiver architectures. First, three different architectures for the impulse-radio UWB transceiver are studied, while investigating the power-performance tradeoffs. The paper illustrates that a more power-efficient architecture should perform part of the signal processing in the analog-domain. Next, the multiband UWB transceiver is studied and power-efficient circuits for the front-end of the UWB transceiver are presented. Finally, the performance and power consumption of these transceivers are compared and a number of design indications are provided.
