Abstract
An RFID device includes an amplification unit, a demodulator, and a modulator. The amplification unit is configured to amplify a level of a radio signal applied through an antenna, and output an amplification signal. The demodulator is configured to generate an operating voltage by rectifying and amplifying the amplification signal, demodulate the operating voltage, and generate a command signal. The modulator is configured to output a response signal, which corresponds to the command signal, to the antenna.
