GLOBAL JOURNAL OFENGINEERINGSCIENCE ANDRESEARCHES ANALYSIS OF DIGITAL LOGIC CIRCUITS BASED ON CNTFET

This paper addresses at first carbon NanoTubes (CNTs) and importance of CNT over silicon based devices has been discussed and then exploring the recent survey on CNTFET structure. In this work, the performance of carbon Nanotube field effect transistors is evaluated and analysis by using digital logic circuit. We know that CNT had proposed as alternative to silicon CMOS technology.CNT having two types that are one is MOSFET type and other one is Schottky-barrier(SB).both types of CNT conduct electron and holes to showing a p-type and n-type behavior. In this model CNTFET based devices offer high mobility for near ballistic transport and high carrier velocity for fast switching. CNFET based device offering molecular devices of technology that the convention CMOS device leaves off. CNTFET could be more achievable devices in comparison to other nanotechnology. After realization of high performance of device CNTFET using basic logic circuit, use SB-CNTFET to design basic logic circuits.
