CNTFET-based CMOS-like gates and dispersion of characteristics

Résumé

This paper deals with the analysis of characteristic dispersions of CMOS-like logic gates (NOT, NAND2, NOR2) based on carbon nanotube transistors. The analysis is based on available compact models and uses a specific tool. We have simulated and analyzed the impact of diameter variations on the static and dynamic characteristics of gates, especially logic switching threshold voltage and propagation time. An important conclusion is that small variations of nanotube diameters seriously impact these characteristics. We have established the relationships between the thresholds or propagation times and the nanotube diameters. Our work is a first step towards parametric fault modeling for logic circuits based on CNTFETs.
