To enable the integration of the time reference, system techniques are proposed and analyzed, several kinds of integrated time references are reviewed, and mobility-based references are identified as viable 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. Provides system analysis to understand requirements for time/frequency accuracy in wireless sensor networks; Describes system optimization for time references in wireless sensor networks, with ad-hoc modulation schemes and system duty-cycle techniques; Includes an overview of different physical principles for integrated time references; Shows a practical alternative for integrated time-references; Details a competitive solution for temperature compensation of integrated references.Analog circuits and signal processing series.Wireless sensor networksMetal oxide semiconductors, ComplementaryRadio frequency integrated circuitsWireless sensor networks.Metal oxide semiconductors, Complementary.Radio frequency integrated circuits.004Sebastiano Fabio1060839Breems Lucien1762479Makinwa Kofi A.
