Abstract

Quantum-dot cellular automata (QCA) is a domain coupling nano-technology that has drawn significant attention for less power consumption, area, and design overhead. It is able to achieve a high speed over the CMOS technology. Recently, the tendency to design reversible circuits has been expanding because of the reduction in energy dissipation. Hence, the QCA is a crucial candidate for reversible circuits in nano-technology. On the other hand, the addition operator is also considered one of the primary operations in digital and analog circuits due to its wide applications in digital signal processing and computer arithmetic operations. Accordingly, full-adders have become popular and extensively solve mathematical problems more efficiently and faster. They are one of the essential fundamental circuits in most digital processing circuits. Therefore, this article first suggests a novel reversible block called the RF-adder block. Then, an effective reversible adder design is proposed using the recommended reversible RF-adder block. The QCAPro and QCADesigner 2.0.3 tools were employed to assess the effectiveness of the suggested reversible full-adder. The outcomes of energy dissipation for the proposed circuit compared to the best previous structure at three different tunneling energy levels indicate a reduction in the power consumption by 45.55%, 38.82%, and 34.62%, respectively.

基于量子平台的新型纳米级可逆加法器的高效节能设计
量子点元胞自动机(QCA)是一种域耦合纳米技术,由于其功耗、面积和设计开销较小而备受关注。它能够实现比CMOS技术更高的速度。最近,由于能量耗散的减少,设计可逆电路的趋势一直在扩大。因此,QCA是纳米技术中可逆电路的关键候选者。另一方面,加法运算器由于其在数字信号处理和计算机算术运算中的广泛应用,也被认为是数字和模拟电路中的主要运算之一。因此,全加法器已经变得流行,并且更有效、更快地广泛地解决数学问题。它们是大多数数字处理电路中必不可少的基本电路之一。因此,本文首先提出了一种新的可逆块,称为RF加法器块。然后,使用推荐的可逆RF加法器块,提出了一种有效的可逆加法器设计。QCAPro和QCADesigner 2.0.3工具用于评估建议的可逆全加器的有效性。与之前的最佳结构相比,在三个不同的隧道能级下,所提出的电路的能量耗散结果表明,功耗分别降低了45.55%、38.82%和34.62%。
