The scaling down of devices has been the driving force towards technological advancements. Dimension of individual devices in an integrated circuit followed Moore's law. Today, silicon based MOSFETs (Metal-Oxide Semiconductor Field Effect Transistors) have technology sizes less than 60nm are common in the world of electronics. As the size become smaller, scaling the silicon MOSFET becomes increasingly harder. In this paper, at first a brief review of Carbon Nano-Tubes (CNTs) is given and then an extensive survey of CNTFET (Carbon Nano-Tube Field Effect Transistor) based logic circuits are discussed with the most recently reported CNTFET logic circuits.
