Mobility-based time references for wireless sensor networks

This book describes the use of low-power low-cost and extremely small radios to provide essential time reference for wireless sensor networks. The authorsexplain how to integrate such radios in a standard CMOS process to reduce both cost and size, while focusing on the challenge of designing a fully integrated time reference for such radios. To enable the integration of the time reference, system techniques are proposed and analyzed, several kinds of integratedtime references are reviewed, and mobility-based references are identified asviable candidates to provide the required accuracy at low-power consumption. Practical implementations of a mobility-based oscillator and a temperature sensor are also presented, which demonstrate the required accuracy over a wide temperature range, while drawing 51-uW from a 1.2-V supply in a 65-nm CMOS process.
