Pages: 174 - 180
Gate All-Around Carbon Nanotube Field Effect Transistor (GAA-CNTFET) is one of the promising transistors to substitute traditional MOSFET. This paper presents universal logic gates based on GAA-CNTFET with different chiral indexes and different number of channel selection for high speed and low power digital application. The simulation tool is used for design and simulation of GAA-CNTFET based basic logic gates. The power consumption and total delay for basic logic gates is calculated for different chirality indexes and different channel selection. From our results, we report that when we increase the chiral vector of CNT; delay increases in digital logic gates. Single chirality (25, 25, 0) based digital logic gates provide minimum delay, similarly dual chirality (25, 22, 0) type digital logic gates exhibits minimum delay. Whereas (14, 14, 0) and (16, 14, 0) chirality delivers low power consumption. © 2018 IEEE.
