“…The input is always set to clock0 and the output clock can be any clock out of four. In any clock pulse each clock cycle in it consists of four phases that is switch, hold, release and relax [24][25][26][27]. The clock phases change due to the tunnel present in QCA cell, which is like a potential barrier in the cell as shown in Fig.…”

Quantum Dot Cellular Automata (QCA) is a prominent technology in Quantum Electronics. This is implemented with the help of quantum cells which are also known as basic building blocks of Quantum Electronics. In QCA technology there are four different clock pulses, clock delay for each clock cycle is 0.25 ns. Using this technology now we are implementing the Binary to Gray code converter. In this paper, we are proposing a design to reduce the number of cells when compared to the previous designs and we are also extending the implementation of the converter up to 5-bits. The number of cells in the proposed design is improved by 2.5%, 36.44%, and 50.66% for 2-bit, 3-bit, and 4-bit respectively. Also, for 3-bit and 4-bit, the total occupied area is improved by 55.56% and 74.680% respectively. In our proposed design it helps us to decrease the area from the previous circuit, which may also lead to the decrease in the power consumption.

For immense demand of speedy high-end gadgets, chips are becoming denser, but Moore's law is falling flat lately. Complementary Metal-Oxide-Semiconductor (CMOS) technology is on its brink. Quantum-dot cellular automata (QCA) has become a potential alternative technology to provide faster speed with low power dissipation at nano-scale extent. Here, we proposed an efficient QCA design of 1-bit comparator. The proposed comparator required 59% less area and dissipated 82% less energy. QCA Designer has been used to design and simulate the proposed comparator. Finally, QCAPro tool has been employed for estimating energy dissipation.

In recent years Quantum-dot Cellular Automata (QCA) has been considered one of the emerging nano-technology for future generation digital circuits and systems. QCA technology is a promising alternative to Complementary Metal Oxide Semiconductor (CMOS) technology. Thus, QCA offers a novel electronics paradigm for information processing and communication system. It has attractive features such as faster speed, higher scale integration, higher switching frequency, smaller size and low power consumption compared to the transistor based technology. It is projected as a promising nanotechnology for future Integrated Circuits (ICs). A quantum dot cellular automaton complex gate is composed from simple 3-input majority gate. In this paper, a 8-3 encoder circuit is proposed based on QCA logic gates: the 4-input Majority Voter (MV) OR gate. This 7-input gate can be configured into many useful gate structures such as a 4-input AND gate, a 4-input OR gate, 2-input AND and 2-input OR gates, 2-input complex gates, multi-input complex gates. The proposed circuit has a promising future in the area of nano-computing information processing system and can be stimulated with higher digital applications in QCA.
