“…The Quantum-dot Cellular Automata (QCA) technology is an emerging and promising technology to these issues at nano-scale [1]. The basic element in this technology is a square cell that has two free electrons in four dots [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The QCA cell is a building block for constructing QCA gates [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

“…There are three basic gates in this technology: inverter gate, majority (M) gate, and XOR gate [3][4]. These gates are building blocks for constructing the logic circuits such as QCA multiplexers [5,7], QCA full address [1-3, 6, 8] and QCA comparators [9][10][11][12][15][16][17][18].…”

“…On the other hand, the comparator circuits play an important role in digital circuits such as micro controllers [6,12,[15][16][17][18]. Thus, the implementation of high-performance comparator circuits has a great deal of attention, and a lot of effort [10][11][12][15][16][17][18] has been invested in performance improvement in the QCA comparator circuits. Das and De [10] have presented a 1-bit QCA comparator that requires 0.343 µm 2 area and 319 QCA cells.…”

QCA technology is an emerging and promising technology for implementation of digital circuits in nano-scale. The comparator circuits play an important role in digital circuits. In this work, a new and efficient coplanar 1-bit comparator circuit is proposed and evaluated in the QCA technology. The designed coplanar 1-bit QCA comparator circuit is constructed based on majority gate, XNOR gate and inverter gate that are designed carefully. The functionality of the designed coplanar 1-bit QCA comparator circuit is verified by using QCADesigner version 2.0.3. The obtained results indicate that the designed 1-bit QCA comparator circuit requires 0.03 µm 2 area and 38 QCA cells. It also has 0.5 clock cycles delay. The comparison demonstrates that the designed QCA comparator circuit provides improvements in comparison with other QCA comparator circuits in terms of effective area, cell count, and delay as well as cost.

“…QCA is an emergent archetype which offers an advanced method for logic circuits [3][4][5][6]. QCA proposed an enhanced comprehensive computational function by the lateral of the nanoscale [7][8][9] through modifying the fact of a precise electron of this archetype promise advance minimal power, extreme rapidity with particularly compact circuits. Reversible logic gates such as Toffoli gate [10], Double Feynman gate (F2G) [11], Peres gate [12], Fredkin gate [13] and Multiply Complements Logic [14] gates have been designed in QCA.…”
