Abstract
This work presents an ultra low-power duty-cycled wake-up radio system for high-data-rate, short-range millimeter-wave WPAN applications. The asynchronous duty-cycled wake-up power management method is proposed and optimized to reduce the average power consumption. As the design example, a 60 GHz radio system is discussed, which consists of a 4-path phase-array transceiver, a duty-cycled wake-up receiver and the digital control circuits. Theoretical analyses of the optimum duty-cycle factor towards minimum average power are shown accordingly. Simulation results are given and a 230 µW average power consumption is achieved for the entire radio, which leads to about 4000-hour operation time for a 1.5-V 1000-mAh re-chargeable battery.
