Quantum Cellular Automata based Novel Unit 2:1 Multiplexer

Abstract

Quantum Cellular Automata (QCA) is an emerging nanotechnology and one of the top six technologies of the future. CMOS technology has a lot of limitations while scaling into a nano-level. QCA technology is a perfect replacement of CMOS technology with no such limitations. In this paper we have proposed one 2:1 multiplexer circuit having lowest complexity and area compared to the existing QCA based approaches. The proposed design is verified using QCADesigner.

Design of Adder Using Quantum Cellular Automata

“…Finally, full adder structure requires five majority gates and three basic inverters [9] which is shown in fig.6. Fig.6 Basic Full adder using Majority gates K. Navi [10] has proposed different logical expression which is given in the eq.7 ,eq.8 and its logical diagram is shown in fig.7. ) , , ( c b a f Carry  (7) ) , , , , ( From [10] adders is developed by utilizing 3 input XOR gate [18] and five input majority gate. The 3 input XOR based on QCA is shown in fig.8 comprising 14 cells and assign one of the input is zero which behaves as an XOR gate.…”

“…In [2], it explains how to implement QCA circuits using majority gate and inverter gate. With these we can implement basic circuits, adders [4], mux [6,7], flip-flops [5], etc… Adders are the fundamental element in the ALU's and Multiplications Units. The adder block is implemented by XOR, AND logic gates which performs binary arithmetic operations.…”

Power analysis dataset for QCA based multiplexer circuits

“…In this paper, power dissipation analysis of different multiplexer circuits presented in [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], have been investigated in Table 1 at three different tunneling energy levels like $\gamma =0.5E_k,\gamma =1.0E_k$ and $\gamma =1.5E_k.$ The energy dissipation map which includes leakage power dissipation, switching power dissipation and average power dissipation of various QCA multiplexers have been shown in Fig. 1.…”

Design of Novel Efficient Multiplexer Architecture for Quantum-dot Cellular Automata

“…They have proposed hierarchical layout methods which combines fundamental QCA devices into more complex devices. After that, several efforts has been presented with target to improve the design of 2:1 QCA multiplexer architectures [1], [10][11][12][13][14][15][16][17][18][19][20], [23], 4:1 QCA multiplexer architectures [1,12,14,15,18,20,21,24,25,29,30], and 8:1 QCA multiplexer architectures [1,15,18,21,29] in terms of number of cells and delay in the QCA technology.…”
