Abstract

Various phenomena are to be minimized, particularly the loss of bandwidth at the minimum gate for VLSI when the minimum gate length decreases below a limiting length. Which results in lower efficiency and higher baseline power consumption, pointing towards the death knell of Moore’s law. Unlike silicon-based MOSFETs, carbon nanotube field- effect transistors (CNTFETs) are one of the potential candidates for next-generation transistors owing to their improved carrier mobility and reduced power loss. The integration of CNTFETs in VLSI technology is discussed in this work, which had considerable improvement in integration density and enhanced the power dissipation but involved the expensive process of fabrication and stability. Optimized CNTFETs exhibit significant advantages over their counterparts, i.e., MOSFETs, in terms of device modeling, simulations, and technological comparisons. In terms of performance, they provide 18 × faster switching speed, a good on-off current ratio, reaching 106, 28% less dynamic power dissipated, and up to 35% less static power dissipated. In summary, CNTFETs have a significant potential for use in future semiconductor technologies, overcoming the limitations of traditional silicon-based transistors.
