基于量子元胞自动机的n位全加器设计
Design of n-bit Full Adder Based on Quantum-Dot Cellular Automata
摘要
Abstract
Quantum-dot cellular automata(QCA)is considered as an emerging technology,because of its unique characteristics such as low power consumption,nanoscale design,and high computing speed,which can be used as an alter-native for CMOS technology in circuit design for quantum computers in the near future.In recent years,many FAs(Full Adder)are designed using three-input majority gate(M3)and three-input XOR gate(XOR3)in QCA circuits.Three new types of n-bit full adders(FA1,FA2 and FA3)are designed based on these two logic gates and the unique clock characteris-tics of QCA circuits in this paper.FA1 is implemented using only a 1-bit FA,and its cell number and circuit area are re-duced by at least 78%and 90%by comparing with the published 8-bit FA.But FA1 can only calculate one bit in one clock cycle,so it has a large delay.The number of cells and circuit area of FA2 are reduced by at least 47%and 63%by compar-ing with the published 8-bit full adder.And FA2 can calculate two bits in one clock cycle.FA3 can perform four-bit calcu-lations in one clock cycle with minimum delay.As n-bit full adders,the number of cells and circuit area of FA1,FA2 and FA3 will not change with the increase of the number n,which can't be realized by the previous design.关键词
