Simulation and Design of Organic RFID Based on Dual-Gate OFET

A dual-gate OFET model and its multi-platform analog/digital active library of organic RFID is presented. The zero-VGS inverters implemented by dual-gate OFET and single gate OFET are discussed and analyzed, as well as two architectures of the dual-gate OFET inverter are presented, which shows the dual-gate OFET model improving the performances of the inverter such as larger noise margin and higher gain. Furthermore, the simulations of ring oscillator and full RFID tag system by different inverter implementations are compared and discussed. The dual-gate OFET solution can provide a post-fabrication tunability to optimize the clock frequency and tag data rate in some extent.
