Abstract
Ultra-wideband (UWB) communications is currently being explored as a medium for high-data-rate last-meter wireless links. Accordingly, there has been much interest in integrating UWB radios onto battery-operated devices, creating a strong demand for energy efficient UWB systems. The objective of this work is to describe how operating the digital baseband processor in the sub-threshold region and increasing the degree of parallelism can translate into energy savings across the entire UWB receiver. While sub-threshold operation is traditionally used for low energy, low performance applications such as wrist-watches, this work examines how sub-threshold operation can be applied to low energy, high performance applications. Simulation results for a 100-Mbps UWB baseband processor using the digital logic cell library of a 90-nm process are presented.
