Abstract

This paper presents a comparison of temperature dependence of I-V characteristics in CarbonNanotube Field Effect Transistors (CNTFETs) models proposed in the literature in order to identifythe one more easily implementable in simulation software for electronic circuit design. At first weconsider a compact, semi-empirical model, already proposed by us, performing I-V characteristicsimulations at different temperatures. Our results are compared with those obtained with two othermodels: the numerical FETToy model and the Stanford-Source Virtual Carbon Nanotube Field-EffectTransistor model (VS-CNFET), obtaining I-V characteristics comparable with those of two examinedmodels, but with CPU calculation times much lower.
