This paper presents an implementation of radio-triggered circuit to decrease energy consumption of active RFID tag.A radio-triggered circuit is added to a traditional active tag.Active tag stays in sleep mode until Reader sends Radio Wake-up signal.Active Tag can save a lot of energy then prolong its lifespan by adopting this working mode.The simulating results demonstrate that the sensitivity of the circuit can reach -45.2 dBm,which means that the reader can wake up tags about 30 meters away.The energy consumption of this circuit is only 4.11 μW.These features can meet the requirements of many applications.

Key words: radio frequency identification(RFID);radio wake up;low power consumption;active tag
