Review—Thermal Effects in the Design of CNTFET-Based Digital Circuits

In this paper we review a method to analyse the thermal effects in the design of CNTFET-based digital circuits, enhancing a compact model, already proposed by us, in which the temperature variation in the drain current equation and in energy band gap is considered. At first the impact of temperature variations on design parameters of CNTFET is shown, with particular reference to the output and trans-characteristics, the output resistance, the transconductance. Then, using ADS software, the effects of temperature variations in the design of some digital circuits, are illustrated and widely discussed, emphasizing that the reviewed procedure can easily be applied to any other circuit based on CNTFET.
