摘要

作为一种新型的纳米器件，量子元胞自动机（Quantum-dot cellular automata，QCA）有望取代传统CMOS器件.本文总结了目前已提出的三种全加器（Full Adder，FA）架构，通过概率转移矩阵（Probabilistic Transfer Matrix，PTM）分析找出其中最稳定的架构，进一步地，利用这三种全加器分别构建串行加法器，并从复杂度、不可逆功耗、成本等方面进行比较，结果发现性能最优的全加器架构为MR Azghadi FA.随后，选择该架构提出了一种针对全加器的新型逻辑门和共面QCA全加器电路，并应用此全加器设计了多位串行加法器，经对比分析表明，本文所提出的全加器电路在面积、元胞数和功耗等方面均有较大改进，且具有很好的扩展性.

Abstract

Quantum-dot cellular automata (QCA)

a burgeoning technology at nano-scale range

has the potential to take the important place of CMOS technology to be the next IC technique.In this paper

three existing schemes of QCA full adders (FAs) are analyzed in detail using probabilistic transfer matrix (PTM) to find out the most robust one.Three types of n-bit carry flow adders connected serially by these three FAs respectively are also analyzed in terms of complexity

irreversible power dissipation and cost to find out the corresponding FA scheme with best performance.It turns out that MR Azghadi FA always performs well by these two means.With MR Azghadi FA layout

a new logical gate and coplanar QCA FA are then proposed.Analysis and comparison with previous coplanar FAs demonstrate that the proposed FA has a great optimization with respect to area

cell count and power dissipation and also has favorable scalability.
