<span lang="EN-US">The high-performance digital circuits can be constructed at high operating frequency, reduced power dissipation, portability, and large density. Using conventional complementary-metal-oxide-semiconductor (CMOS) design process, it is quite difficult to achieve ultra-high-speed due scaling problems. Recently quantum dot cellular automata (QCA) are prosed develop logic ato...

Quantum-dot cellular automata (QCA) is one of the best methods to implement digital circuits at nanoscale. It has excellent potential with high density, fast switching speed, and low energy consumption. Researchers have emphasized reducing number gates, delay, cell count in QCA technology. In addition, a ripple carry adder (RCA) circuit which each full adder's carry-out connection for next carr...

Abstract Quantum-dot Cellular Automata (QCA) is a rival to complementary-metal-oxide-semiconductor (CMOS)-based technology and one of the most cutting-edge nano-scale technologies. The multiplexer fundamental component in fields nano communication computation. investigative item this article QCA multiplexer, handful best multiplexers were chosen as samples for current experiment. layouts design...

Quantum dot Cellular Automata (QCA) is one of the most popular nano-technology, with the potential for faster speed, lower power consumption and smaller size than the latest CMOS technology. One of the basic building blocks of QCA circuits is QCA wire. The conventional QCA wires require more cells and it has less polarization. In this paper, we have designed high polarized wires using minimum n...

We present an experimental demonstration of a fanout gate for quantum-dot cellular automata (QCA), where a signal applied to a single input cell is amplified by that cell and sent to two output cells. Each cell is a single-electron latch composed of three metal dots, which are connected in series by tunnel junctions. Binary information is represented by an excess electron localized to one of th...

The simplest graph drawing method is that of putting the vertices of a graph on a line (spine) and drawing the edges as half-circles in κ half planes. Such drawings are called κ-page book drawings. Edge crossing minimisation is the most important goal in linear Very Large Scale Integration (VLSI) circuit design and Quantum-dot Cellular Automata (QCA), since a smaller number of crossings means l...

Abstract—The construct of computing is the field of ever improving and advancing systems and architectures. One of the emerging archetype that has made its ground as a research area is the concept of reversible logic in computing. Reversible logic suggests the systems with zero heat dissipation since the computational models in this logic incorporate the concept of reversibility at a ground lev...

Design of parity preserving logic based on emerging nanotechnology is very limited due to present technological limitation in tackling its high error rate. In this work, Quantum-dot cellular automata (QCA), a potential alternative to CMOS, is investigated for designing easily testable logic circuit. A novel self-testable logic structure referred to as the testable-QCA (t-QCA), using parity pres...

The atomistic quantum-dot cellular automata (QCA) based implementations of the reversible circuits have got tremendous exposures in the last few days, due to “room-temperature workability” of the QCA. The researchers are in serious need of a methodology that can realize the area-efficient QCA counterparts of reversible benchmark circuits. In this work, a novel methodology named majoritylayered ...
