Abstract :
RFID systems operating at a base carrier frequency of 13.56 MHz can use low-cost inductive antennas on foil. In parallel to this coil, a capacitor on foil is used for matching the resonance frequency at 13.56 MHz. This LC-antenna detects the signal transmitted by the reader and energizes the organic rectifier with an AC-voltage at 13.56 MHz. From this voltage the rectifier generates the DC supply voltage for the 64 b organic transponder chip, which drives the modulation transistor between the on and off state with a 64b code sequence.
