In this paper we analyse the impact of temperature variations on design parameters of CNTFET with particular reference to the output and trans-characteristics, the output resistance, the transconductance and cut-off frequency. The analysis of CNTFET I-V characteristics allows to say that, except for the transition regions, there are very slight differences with temperature variations., Paper published in International Journal of Advances in Engineering & Technology (IJAET), Volume 14 Issue 4, pp. 44-51, August 2021.
