dc.description.abstract | "An energy autonomous active wireless surface acoustic wave (SAW) temperature sensor system is presented in this paper. The proposed system adopts direct temperature to frequency conversion using a lithium niobate SAW resonator for both temperature sensing and high-Q resonator core in a cross-coupled RF oscillator. This arrangement simplifies the temperature sensor readout circuit design and reduces the overall system power consumption. A power conditioning circuit based on buck-boost converter is utilized to provide high efficiency power extraction from piezoelectric energy harvester (PEH) and dynamic system power control. The SAW resonator is fabricated in-house using a two-step lithography procedure while the RF oscillator as well as the PEH power conditioning circuit are implemented in standard 65-nm and 0.18- mu m CMOS processes respectively. The measured RF transmitter output power is -15 dBm with a phase noise of -99.4 dBc/Hz at 1 kHz offset, achieving a figure of merit (FOM) of -217.6 dB. The measured temperature sensing accuracy is +/- 0.6 degrees C in -40 degrees C to 120 degrees C range. Fully powered by a vibration PEH, the proposed energy autonomous system has a self-startup voltage of 0.7 V and consumes an average power of 61.5 mu W." | - |
