DC/AC unified OTFT compact modeling and circuit design for RFID applications

Organic materials and devices are gaining more and more attention in microelectronics. They are dedicated to low cost applications and easy in fabrications. Device structure and organic material characteristics are key points to achieve targeted products. Considering technology and product specifications, compact organic device modeling and circuit design are necessary to evaluate technology performance in RFID tags. This model is based on variable range hopping theory (VRH), i.e., a carrier may either hop over a small distance with a high activation energy or hop over a long distance with a low activation energy. The model has been developed using a physical basis where the model parameters can easily be extracted and it improves convergence in circuit simulations. It is also suitable for computer aided design (CAD) applications. (c) 2007 Elsevier Ltd. All rights reserved.
