TCAS-I 1611Abstract-This paper presents the first printed organic 13-MHz RFID on flexible substrate. The proposed solution includes a planar near field antenna bonded to an RFID tag, which is printed on flexible foil using an organic complementary TFT technology. Thanks to an active envelope detector, ASK modulation with modulation depth as low as 20% can be adopted to increase the available input power for the rectifier. The RFID functionality is demonstrated at the internally generated supply voltage of 24 V, for a reading range of 2-5 cm and a bit-rate up to 50 bit/s. With more than 250 transistors on the same foil, this work represents the most complex circuit ever published in a printed organic complementary TFT technology.Index Terms-ASK modulation, active detection, mixed analog-digital circuits modulation index, organic circuits, pentacene, polyimide, radio frequency identification, sub...
