“…Khan and Mandal have introduced a new and most straightforward architecture of 2 to 1 multiplexer in QCA; 2 to 1 multiplexer is implemented with the lowest area of layout and number of cells. In this work, the kink energy is calculated for the proposed circuit, and the analysis of the effect of the hazard has been done successfully.…”

“…A first fundamental and essential logic gate in QCA is an Inverter, which changes the value of input from one logic value to another. Normally, two kinds of inverters are used (Abutaleb, 2020; Khan and Mandal, 2019), which are applied for operation in lots of designs as a single cell, as shown in the literature (Safoev and Jeon, 2020; Kassa and Nagaria, 2017).…”

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.

“…Figure 2B, includes the crossover of cells in clock zone 0 and zone 2, while cells in clock zone 1 and zone 3 are used in the third process, as shown in Figure 2C. Over the last decade, QCA technology has been frequently used for designing different digital circuits such as adders, 5,6 multiplexers, [7][8][9][10][11] switching circuits, [12][13][14] reversible logic, 1,4,15-17 sequential circuits, [18][19][20][21] etc. One such application area considered in this paper is the design of coplanar random access memories.…”

In this paper, a loop based coplanar random access memory (RAM) cell with set/reset ability using quantum‐dot cellular automata (QCA) technology is first proposed. The operation of the RAM cell is validated physically as well as by simulations using QCADesigner tool. The energy dissipation analysis of the proposed RAM cell demonstrates that the proposed design dissipates very low energy. Additionally, the fault tolerance to single cell missing and addition defects of the proposed RAM cell is also presented. Further, we designed a coplanar 1 × 4 RAM which consists of four proposed RAM cells, one 2:4 decoder and one 5‐input majority voter along with the control signals required for the proper operation of the RAM. The proposed RAM cell and 1 × 4 RAM designs achieve performance improvement of up to 88.16% and 79.28%, respectively from the existing design in terms of QCA circuit cost. These structures can therefore be used to design efficient higher order RAM structures.
