This work compares the different tools available in nanoHUB for the electrical simulation of carbon- based field-effect transistors made up of either carbon nanotubes (CNTs) or graphene. Among others, the following tools are considered: CNTbands, CNTFET lab, FETToy and GFET tools. Electrical (I-V) characteristics are simulated by using these tools and compared with those obtained by reported models for SPICE-like electrical simulators. Main figures are compared from a circuit designer’s viewpoint, in terms of main performance metrics, accuracy, reliability and design parameters for their use in practical circuit design.


José M. de la Rosa received the M.S. degree in Physics in 1993 and the Ph.D. degree in Microelectronics in 2000, both from the University of Seville, Spain. Since 1993 he has been working at the Institute of Microelectronics of Seville (IMSE), which is in turn part of the Spanish Microelectronics Center (CNM) of the Spanish National Research Council (CSIC), where he heads a research group on micro/nanoelectronic circuits and systems. He is also with the Department of Electronics and Electromagnetism of the University of Seville, where he is currently a Professor.

His main research interests are in the field of analog and mixed-signal integrated circuits, including analysis, behavioral modeling, and design automation of such circuits. In these topics, Dr. de la Rosa has participated in a number of National and European research and industrial projects, and has co-authored 5 books and some 200 international peer-reviewed publications, including journal, conference papers and book chapters.
