Abstract: A device and a method for detecting wakeup burst in an active RFID(Radio Frequency IDentification) tag are provided to reduce power consumption of the active RFID tag by activating the active RFID tag based on the wakeup burst detected from a signal, which is received from an RFID reader, when the RFID tag starts communication. A trigger signal generator(110) generates trigger signals continuously at predetermined intervals by responding to an input signal received from an RFID reader, and a counter(120) is activated by receiving one of the generated trigger signals and counts sub burst of the input signal while the trigger signal is kept. A comparator(130) detects whether the input signal is wakeup burst depending on matching between a counted value and a predetermined reference value. A wakeup signal generator(140) generates a wakeup signal when all values counted while each trigger signal is kept are matched with the reference value. A reset unit(150) disables the trigger signal generator and the counter when the counted value is different from the reference value.

Abstract: A device and a method for managing power of a passive tag are provided to use a battery embedded in the passive RFID(Radio Frequency IDentification) tag when an RF power level is insufficient to drive the passive RFID tag by measuring intensity of an RF signal received from an RFID reader. A power supply unit(100) supplies driving power of an RFID tag according to a predetermined control. A power receiver(110) receives an RF signal from an RFID reader. A power manager(120) measures intensity of the received RF signal, and supplies the driving power to the RFID tag by using the power output from the power supply unit or the power induced from the RF signal depending on the control corresponding to a measurement result. The power manager measures a voltage level of the received RF signal, and a controller(130) enables the power manager to supply the power induced from the RF signal when the measured voltage level is higher than a predetermined level capable of driving the RFID tag. The first received command from the RF signal of the RFID tag is used to measure intensity, and the second received command is used to communicate with the reader.

Abstract: An apparatus and a method for generating a wake-up signal of a passive tag having a battery are provided to adjust a life span of a battery or a tag by generating a wake-up signal which operates the battery in response to a signal of an RFID(Radio Frequency Identifier) reader. An apparatus for generating a wake-up signal of a passive tag having a battery includes a signal detection unit(200), and a control unit(250). The signal detection unit generates a wake-up signal if an input signal is an activation command signal by measuring a holding time between pulses or a period of the pulse based on a coding mechanism of the input signal of an RFID reader. The control unit activates a power supply function of the battery by the wake-up signal. The signal detection unit has a first signal detection unit(210) and a second signal detection unit(237). If the preamble of the input signal has a specific data value, the first signal detection unit determines whether the input signal is the activation command signal, and generates an activation check signal. The second signal detection unit compares an activation mask of the input signal with a previously stored activation code in response to the activation check signal. The second signal detection unit generates the wake-up signal if the activation mask is the same with the activation code.

Abstract: An apparatus and a method for managing power of an RFID(Radio Frequency IDentification) tag are provided to reduce power consumption of the RFID tag by measuring the strength of an RF signal received from an RFID reader and adjusting a level of transmission power according to the measured strength. A method for managing power of an RFID tag comprises the following several steps. An RFID tag receives an RF signal from an RFID reader wherein the received RF signal can be a signal for requesting tag information(S310). The received RF signal is converted into a digital signal and power strength of the converted digital signal is measured(S320). A preset power level is designated according to the measured power strength of the received RF signal(S330). A level of transmission power is set up with respect to a response signal to be transmitted to an RFID reader by processing data included in the RFID signal and accessing a memory(S340). The RFID tag transmits a generated response signal to the RFID reader in accordance with the set level of the transmission power(S350).
