Abstract:A duty-cycled PLL operating in burst mode is presented. It is an essential building block of a moderately accurate low-power frequency synthesizer suitable for use in nodes for Wireless Sensor Networks. Once in lock, the PLL's frequency error is less than 0.1% (rms). Fabricated in a baseline 65 nm CMOS process, the PLL occupies 0.19X0.15 mm2 and draws 200 ¹A from a 1.3-V supply when generating a 1 GHz signal with a duty cycle of 10%.
