Restoring and non-restoring divider has become widely applicability in the era of digital computing application due to its computation speed. In this paper, we have proposed the design of divider of different architecture for the computation of Vedic sutra based. The design of divider in the Vedic mode results in high computation throughput due to its replica architecture, where latency is mini...

The quantum-dot cellular automata (QCA) is considered as an alternative tocomplementary metal oxide semiconductor (CMOS) technology based on physicalphenomena like Coulomb interaction to overcome the physical limitations of thistechnology. The decoder is one of the important components in digital circuits, whichcan be used in more comprehensive circuits such as full adde...

Further downscaling of CMOS technology becomes challenging as it faces limitation of feature size reduction. Quantum-dot cellular automata (QCA), a potential alternative to CMOS, promises efficient digital design at nanoscale. Investigations on the reduction of QCA primitives (majority gates and inverters) for various adders are limited, and very few designs exist for reference. As a result, de...

Quantum-dot Cellular Automata (QCA) seek potential benefits over CMOS devices such as low power consumption, small dimensions, and high speed operation. Two prominent QCA concerns of wire crossing complexity and circuit robustness are addressed by developing a three-step Bilayer Logic Decomposition (BLD) methodology to design QCA-based logic circuits. The partitioning of QCA computing operation...

In this article, a new approach for the efficient design of quantum-dot cellular automata (QCA) circuits is introduced. The main advantages of the proposed idea are the reduced number of QCA cells as well as increased speed, reduced power dissipation and improved cell area. In many cases, one needs to double the effect of a particular inter median signal. State-of-the-art designs utilize a kind...

We investigate the effect of a finite temperature on the behavior of logic circuits based on the principle of Quantum Cellular Automata (QCA) and of ground state computation. In particular, we focus on the error probability for a wire of QCA cells that propagates a logic state. A numerical model and an analytical, more approximate, model are presented for the evaluation of the partition functio...

Quantum-Dot Cellular Automata (QCAs) are becoming more and more one of the most promising candidates for the alternative processing platform of the future. Since their advent in the early 1990s the required technological processes, as well as the QCA structures that implement the basic and functionally complete set of binary logic functions, have been developed. This article, however, presents ...

In recent years low power and small size are the keyword in the IC industry. This is where the importance of reversible gate and QCA (Quantum dot cellular automata) comes in. In nonreversible gates there is a definite amount of power loss involved. Interest in reversible computation arises from the desire to reduce heat dissipation, thereby allowing – higher densities and higher speed. The QCA ...
