“…In addition to this, energy analysis has also been done by using QCADesigner‐E tool, 44 which is an extension of QCADesigner tool; however, it also implements the estimation of energy dissipation of QCA circuits based on the previous studies 43,45,46 . In this, it is assumed that QCA cells form a “bath” of energy when separated for each clock cycle, and total energy dissipation is estimated as the sum of all energies of E bath , where E bath is the sum of energy transfers to the QCA bath.…”

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.

“…The schematic of Fredkin and Feynman proposed gates are illustrated in Fig.5 and output waveforms of these gates are shown in Fig.6 which is simulated by using QCADesigner tool. Table 4 and Table 5 presents the QCA layout comparison between the exiting design [19] and the proposed design of the Fredkin and Feynman gate respectively. Energy dissipation can be calculated using QCA Designer-E [20] on considering the parameters shown in fig.10.…”

In the Current scenario of higher level of integration the most encountered problems are heat dissipation and information loss on each and every computation. For the sake of eliminating these issues Reversible computing is being adopted as a preferable substitute of digital circuit design. This paper focuses on the design of Reversible Ring Counter and Twisted Ring Counter using Reversible D flip flop implemented with the Novel Design of Feynman and Fredkin Gate. Ring counters are commonly found in applications used to count the data in a continuous loop as well as in frequency divider circuits. While twisted (or Johnson) ring counter is used as three-phase square wave generators (using 3 flip-flops) and quadrature oscillator circuits (using 2 flip-flops) etc. The response of the proposed counter circuit is tested with the help of QCADesigner 2.0.3 simulation tool and the Energy dissipation is analyzed by the use of QCA Designer-E tool.

“…In the last few years, CMOS technology has facilitated the exponential growth in increase of processing power and feature size; however, the emerging technologies are the need of hour to overcome the physical limitations of CMOS devices. Few of the recent low power technologies include Reversible logic, Adiabatic logic, and Quantum-dot Cellular Automata (QCA) technology [7]. Reversible logic circuits must have one-to-one mapping between input vectors and output vectors; thus the vector of output states can always be used to reconstruct the vector of input states.…”

Considering the roadmap of silicon, the high rate of shrinkage in dimensions of typical MOS circuits, genuine difficulties endanger this innovation. A quantum-dot cellular automaton (QCA) is an outstanding and conceivable answer for substitution of CMOS technology. Sequential circuits contain combinational circuits and memory elements which store binary information. Latches and Flip-flop circuits are the basic components of computerized circuits, along these lines. The area and energy of the sequential circuits has to be minimal for speed applications. Traditional implementation of JK flip-flop circuits requires more cells and consumes more energy. This paper proposes a compact and low energy JK Flip-flop, designed in CAD tool, QCADesigner. Analysis of energy was performed using the CAD tool, QCADesigner-E. The experimental results obtained in the proposed paper demonstrate the reduction in the cell count which in turn brings down the complexity of the circuit when compared to the reference QCA based JK Flip-flop circuits and it also shows a reduction in energy and area.
