Recently we are using carbon nano tube field effect transistor (CNFET), which has short channel effect. CNFET is better than CMOS and FinFET technologies. [3]. In this project Arithmetic and Logic Unit is designed in CNFET 32 nm technology and analyze the power dissipation. Keywords: 4 bit Full Adder, CNFET, FinFET, CMOS, Power dissipation and Delay, ALU. I. INTRODUCTION Electronic researchers are searching possible device for semiconductor industry for best performance. One of the most popular technologies is CNTFET technology which is used in microprocessors and application specific integrated circuits. Fig 1 Structure of CNTFET The CNFET are used in make of logic circuits. It has low resistance and strong interconnects. This paper presents the following sections. Part I provides introduction, Part II provides about CNTFET technology, Part III provides design of logic gates, Part IV provides design of ALU circuits and Part V carries conclusion and future work. II. CNTFET TECHNOLOGY Graphite sheets are rolled into tubs, which is called carbon nano tube. Carbon nano tube field effect transistors are high performance transistors [4].The carbon nano tubes was invented by SumioIijima of NEC Crop in Tokyo. He discovered carbon nano tubes in 1991. Fig 2 Ideal CNTFET Technology Structure 2.1. TYPES OF CNTFET Depending on the chirality, carbon nano tubes are classified into two types. They are single wall carbon nano tubes and multi wall carbon nanotubes. Single wall nano tube is created by a one layer of graphite sheet and multi wall carbon nano tube is made up by multiple layers.
