Pdf An Efficient Quantum Dot Cellular Automata Full Adder In this paper we present a novel design for qca cells and another possible and unconventional scheme for majority gates. by applying these items, the hardware requirements for a qca design can be reduced and circuits can be simpler in level and gate counts. This paper focuses on the design and implementation of a quantum dot cellular automata (qca) based 4 bit binary adder. the adder is a fundamental component in digital computing systems, essential for performing arithmetic operations on binary numbers. Several full adders have been reported in literature but many other qca based circuit implementations, including full subtractor, have not been reported in open literature. comparative study illustrates significant improvements in our design as compared to traditional approaches. Adders, essential for arithmetic operations in modern computing, are a key focus within the qca framework. this work introduces a novel full adder layout featuring a multilayered design with three wire crossings to transfer the binary information in a smooth way without any signal interference.
Pdf Design And Analysis Of Full Adder Circuit In Quantum Dot Cellular Several full adders have been reported in literature but many other qca based circuit implementations, including full subtractor, have not been reported in open literature. comparative study illustrates significant improvements in our design as compared to traditional approaches. Adders, essential for arithmetic operations in modern computing, are a key focus within the qca framework. this work introduces a novel full adder layout featuring a multilayered design with three wire crossings to transfer the binary information in a smooth way without any signal interference. The two adders can be compared and offer good results and irreversible full adder offers a simple approach but the reversible full adder offers a much complex approach and offers more delay. This paper implements three new full adder subtractor circuits with the lowest number of cells, lowest area, lowest latency, and a coplanar (single layer) circuit design, as was shown by comparing the results obtained with those of the best previous works on this topic. The proposed full adder circuit and the proposed ripple adder circuit are compared with previous designs regarding complexity, number of cells, and area and the results are reported. moreover, proposed circuits' power consumption has been calculated by using qcapro. As an alternative to cmos vlsi, researchers have proposed an approach to computing with quantum dots, the quantum cellular automata(qca). quantum dot cellular automata emerged as a new paradigm, beyond current switches to encode binary information.
