A Novel Coplanar Based Adder Logic Design Using QCA

Abstract

Now a days, VLSI is a one of the top most technology are used in the field of electronics communication. It is used to create an integrated circuit by merging million of MOS transistor into a single chip. In VLSI, most of the transistors are design in micro scale level. Now a days people will want all materials are in compact size. So, it is necessary to design a circuit in nanoscale level. In the field of VLSI, CMOS technologies are used for designing a integrated circuit (IC) chips. But in CMOS, size that are used to designing a circuit is in micro scale level. So researcher is introducing new nanotechnology that new technology is called QCA technology. Logic function gate is a one of the fundamental components to design an any circuit in electronics communication. In this paper, novel coplanar approach to designing an efficient QCA based 4-bit full adder using XOR/XNOR logic gate is proposed. QCA Designer Version 2.0.3 simulation tools are used in this proposed method. Performance is analysed and verified to determine the capabilities of proposed full adder.
