In this paper, we present a pentacene-based eight-bit radio frequency identification (RFID) transponder circuit. The circuits are patterned entirely with polymeric shadow masks and operate at carrier frequencies greater than 1 MHz. The thin film integrated circuits were fabricated using methods previously described (P.F. Baude et al., Appl. Phys. Lett., vol.82, p.3964, 2003). In the work reported here, we use an ac powering approach to power the logic and amplitude modulation circuitry. A description of the RFID circuit is given, along with details of the reader. |
