Abstract: A power cut-off apparatus and a method in an RFID system are provided to extend the life span of a battery which is attached to an RFID tag to the maximum by preventing idle current of the tag when signals of an RFID reader do not exists. A power supply unit(206) supplies the power to an RFID tag. An input unit(203) rectifies inputted signals of the predetermined frequency band, and outputs the rectified signals as direct voltage source signals. A wake-up determination unit(204) generates a high or low signal by comparing a voltage value of the direct voltage source to a predetermined standard voltage value. A switch unit(205) interrupts the power provision to the RFID tag when the low signal is generated.

Abstract: A low power consumption RFID(Radio Frequency IDentification) tag for improving coverage and a wake-up method thereof are provided to increase the coverage of the RFID tag and detect a command by detecting continuous wave with a minimum standby current of an internal power supply unit and receiving operation voltage when the continuous wave is detected. A power supply unit(250) supplies the operation voltage. A continuous wave detector(225) detects the continuous wave from a signal received from an RFID tag reader by receiving the operation power from the power supply unit. A command detector(245) receives the operation power selectively and detects the command from the signal. A controller(255) performs the detected command by applying the operation power to the command detector if the continuous wave is detected, and cuts off the operation power applied to the command detector if the command is not received from the command detector for a predetermined time. A wake-up signal detector detects a wake-up signal from the signal if the continuous wave is detected. An RF generator(260) generates and provides an operation RF to the controller by receiving the operation power selectively.

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: A low-power RFID(Radio Frequency IDentification) tag for lengthening a tag life and a method thereof are provided to lengthen life of a battery by operating only the minimum circuit for waking up the RFID tag, and perform operation with voltage of a continuous wave instead of voltage supplied from the internal battery when the voltage of the continuous wave received from an RFID tag reader is sufficient.

A main controller(260) activates the general command decoder, and deactivates the general command decoder when the general command is not received from the general command decoder for a predetermined time in an active mode performing the general command. A wake-up controller(250) switches the main controller into the active mode when a voltage level of a continuous wave included in the signal is higher than a predetermined voltage level or the wake-up command is identical with an activation code while the main controller is kept in a standby mode.
