At the onset of this grant period, the PI proposed to conduct a study of hardware aware low power radio architectures and protocols. It had become increasingly clear that while the communications community had notable ideas for constructing networks of simple low power radios that could be used for ubiquitous sensing tasks, many of these ideas actually required the construction of high power radios. Moreover, the hardware and circuit design community was far more interested in high performance of communication architectures than in trying to develop their own low power protocols that made sense in hardware. As a result, the PI took on the task of merging ideas from communications with low power hardware design as part of an exploration of co-optimized architectures for real self-powered radio systems. The results have been a comprehensive study of CW continuous wave and UWB ultra-wide band approaches which has led to the development of a truly novel UWB architecture which solves many of these problems and may be used in ubiquitous sensor networks. Scientific contributions for the period of this grant are divided into 3 topics. First we address contributions in the area of low power UWB transceiver design. The second topic addressed is design of PLL architectures for low power CW transceiver. The third topic of interest is in the design of new oscillator topologies for low power CW transceivers. Previous technical reports have addressed these topics, and some of that material is contained in this final report. However, since the last report for 2007, there have been significant advances on the topic of UWB design, requiring extension of this topic as a focus of this final report.
