Abstract

Power management is an important technique to prolong the lifetime of wireless sensor network(WSN). A radio-triggered based wake-up circuit is proposed to control the activation and shutting down of the wireless sensor node, and thus eliminates energy wasting wake-up periods. The radio-triggered wake-up circuit is optimized to achieve maximum sensitivity by characterizing both the impedance transformation network and the rectifier circuit. The simulation and measurement results show that the circuit can produce a DC output of 220mV with the received power as low as -27.7dBm.
