Logic Design and Modeling of an Ultraefficient 3 × 3 Reversible Gate for Nanoscale Applications

Quantum dot Cellular Automata based Fault Tolerant Fingerprint Authentication Systems using Reversible Logic Gates

“…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.…”

Design of efficient N‐bit shift register using optimized D flip flop in quantum dot cellular automata technology

“…Over the last decade it has been exhaustively used to design various digital logics such as adders and subtractors [7][8][9][10][11], sequential circuits [12][13][14][15], reversible logic [11,[16][17][18][19][20][21], memories [22][23][24][25][26], code converters [27][28][29][30][31] and image processing [32][33][34][35]. A new optimized design of D flip flop in QCA is first presented which is then used to design 2-, 3-, 4-and 8-bits shift registers which are scalable up to N-bits.…”

QCA based cost efficient coplanar 1 × 4 RAM design with set/reset ability

“…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, 7–11 switching circuits, 12–14 reversible logic, 1,4,15–17 sequential circuits, 18–21 etc. One such application area considered in this paper is the design of coplanar random access memories.…”
