Dynamic Simulation of CNTFET-based Digital Circuits

In this paper we propose a simulation study to carry out dynamic analysis of CNTFET-based digital circuit, introducing in the semi-empirical compact model for CNTFETs, already proposed by us, both the quantum capacitance effects and the sub-threshold currents. To verify the validity of the obtained results, they are compared with those of Wong model. Our model may be easily implemented both in SPICE and in Verilog-A, obtaining, in this last case, the development time in writing the model shorter, the simulation run time much shorter and the software much more concise and clear than Wong model.
