“…RMG gate can be used vigorously in place of the OMG gate for designing QCA circuits for minimizing area, delay and power with improving the overall circuit functionality. Many circuits have been designed in literature, which shows the importance of RMG gate in designing QCA circuits (Hamid and Abdalhossein, 2017; Prakash et al , 2019; Sasamal et al , 2017; Seyedi and Navimipour, 2018; Kandasamy et al , 2018; Fam and Navimipour, 2019).…”

Purpose In nano-scale-based very large scale integration technology, quantum-dot cellular automata (QCA) is considered as a strong and capable technology to replace the well-known complementary metal oxide semiconductor technology. In QCA technique, rotated majority gate (RMG) design is not explored greatly, and therefore, its advantages compared to original majority gate are unnoticed. This paper aims to provide a thorough observation at RMG gate with its capability to build robust circuits. Design/methodology/approach This paper presents a new methodology for structuring reliable 2n-bit full adder (FA) circuit design in QCA utilizing RMG. Mathematical proof is provided for RMG gate structure. A new 1-bit FA circuit design is projected here, which is constructed with RMG gate and clock-zone-based crossover approach in its configuration. Findings A new structure of a FA is projected in this paper. The proposed design uses only 50 number of QCA cells in its implementation with a latency of 3 clock zones. The proposed 1-bit FA design conception has been checked for its structure robustness by designing various 2, 4, 8, 16, 32 and 64-bit FA designs. The proposed FA designs save power from 46.87% to 25.55% at maximum energy dissipation of circuit level, 39.05% to 23.36% at average energy dissipation of circuit-level and 42.03% to 37.18% at average switching energy dissipation of circuit level. Originality/value This paper fulfills the gape of focused research for RMG with its detailed mathematical modeling analysis.

“…Because the energy dissipation during state transition and propagation in QCA is negligible [4][5][6], there is significantly minimal energy dissipation when compared to CMOS technology. QCA is thoroughly investigated, and many logics are being proposed for diverse purposes, including reversible logic [6][7][8][9], arithmetic circuits [4,5,[10][11][12][13][14][15][16], code converters [17][18][19][20][21], sequential circuits [17,[22][23][24][25], memories [26][27][28][29], and so on.…”

“…There is relatively low‐energy dissipation since there is negligible energy dissipation during the propagation and state transition in QCA 4–6 . QCA technology is being explored exhaustively, and various logics such as adders, 7–14 code converters, 15–18 sequential circuits, 19–23 and memories 24–27 are being proposed for various applications. One such area considered of application is secure transmission of information.…”

SummaryIn the current digital era, there is a need of secure and efficient nanocommunication systems with ultralow power consumption. One technology that can be used for designing these systems is the quantum‐dot cellular automata (QCA). In the nanoregime, QCA is able to operate with higher speed and lower power dissipation compared with complementary metal oxide semiconductor technology. This work explores the applicability and feasibility of polar encoders, which felicitates reliable data communication with reduced probability of error, in nanocommunication systems. In this paper, (8,4) polar encoder is proposed in QCA technology. The proposed design is a single‐layer structure designed using only 600 cells consuming cell area of 0.1944 μm2 and total area of 0.7225 μm2 with a latency of 3.75 clock cycles, which results in a cost of 10.16. Based on the performance comparison, it is observed that the proposed design is cost‐efficient and achieves improvement up to 49.49% in terms of number of cells and area consumption, 40% improvement in latency, and 86.42% improvement in terms of cost compared with the only design in the literature. In addition to this, the energy dissipation analysis of the proposed designs is also presented. Hence, the proposed designs can be efficiently utilized in nanocommunication systems requiring minimal area and ultralow power consumption.
