Abstract:

Today OLAE RFID tags are limited in performance. The ORICLA partners elaborate new OLAE chip technologies, based on hybrid complementary logic using p-type organic and n-type solution processed oxide semiconductors. This unique combination leads to demonstration of OLAE chips and tags with performance, getting close to requirements for EPC item level tagging. The month 18 ORICLA demonstrations comprise the integration of the hybrid CMOS process on foil [Rockele et al., Organic Electronics 12,1909 (2011)] and bidirectional communication (i.e. the tag can understand and talk to the reader) with uplink data rates up to 3.5 kbits/s and downlink data rates up to 21 kbits/s [Myny et al, ISSCC 2012]. These results have been demonstrated using solution processed oxides at temperatures as low as 250C. Current work focuses in implementing these hybrid CMOS circuits using the new solution processed oxides developed by EVONIK that can go down to temperatures as low as 150C. These low process temperatures will enable to realize the RFID tag on low-cost PEN foil. A second remaining focus of the ORICLA project is to increase the maximum frequency of the oxide rectifiers up to UHF frequencies. These frequencies allow reducing the cost of the printed antennas, which enables the path to low-cost RFID tags for item level tagging.
