Summary The QCA technology is a promising emerging technology at nano‐scale for replacing CMOS technology. Shift register has a vital role in communication networks and digital electronic circuits that are the main components of integrated circuits and memory. In this study, novel and efficient delay circuit (pseudo‐D‐Latch) is designed. Then, 3‐, 4‐, and 5‐bit SISO QCA shift register architectures are developed and evaluated in single layer, 3‐layer and 5‐layer using the designed delay circuit. The designed architectures are evaluated using QCADesigner‐E tool version 2.2. The results demonstrate that the pseudo‐D‐Latch circuit contains 17 cells and 0.01 μm2 area. The 3‐, 4‐, and 5‐bit single layer SISO QCA shift register architecture contains 63 (0.05 μm2), 85 (0.66 μm2), and 107 (0.08 μm2) cells (area), respectively. The 3‐ and 4‐bit 3‐layer SISO QCA shift register architecture contains 63 (0.03 μm2) and 84 (0.03 μm2) cells (area), respectively. The 3‐ and 5‐bit 5‐layer SISO QCA shift register architecture contains 62 (0.02 μm2) and 105 (0.032 μm2) cells (area), respectively. These results show that the designed QCA architectures provide improvements compared with other SISO QCA architectures.

“…[4][5][6] The info in QCA technology has been conveyed after propagating polarization among two cells because of the electrons' Coulombic interaction. [6][7][8][9] An alteration in the logic amount in QCA does not discharge the capacitor, unlike conventional CMOS. Thus, it makes QCA more suitable for designing nanocircuits over CMOS technology.…”

Recently, quantum dot-cellular automata (QCA) has fascinated much attention because of its potential less area consumption, low power usage, less intricacy, and low delay. The full-adder circuit is used in this technology for several procedures, like multiplication, subtraction, and division in the arithmetic logic unit. For this reason, the full-adder is generally investigated as a central unit in the development of QCA technology. The present investigation demonstrates a new efficient QCA-based full-adder layout utilizing the TIEO gate and new 3-input majority gate. In this design, the inputs get inside one side, and the outputs are derived from another circuit side. Other cells do not embrace the output and input signals, and they may simply be available, helping produce a more impressive circuit layout. Concretely speaking, in this design, the 0.02 μm 2 region and the latency of the 0.5 clock cycle have been implemented using only 18 cells. Utilizing the QCADesigner tool, the suggested design in the current investigation has been functionally approved. The simulation outcomes show that this layout conducts properly and works faster than the oldest designs.

Quantum‐dot cellular automata (QCA) is an alternative complementary metal‐oxide‐semiconductor (CMOS) technology that is used to implement high‐speed logical circuits at the atomic or molecular scale. In this study, an optimal 2‐to‐4 decoder in QCA is presented. The proposed QCA decoder is designed using a new formulation based on the MV32 gate. Notably, the MV32 gate has three inputs and two outputs, which is equivalent two 3‐input majority gates, and operates based on cellular interactions. A multilayer design is suggested for the proposed decoder. Subsequently, a new and efficient 3‐to‐8 QCA decoder architecture is presented using the proposed 2‐to‐4 QCA decoder. The simulation results of the QCADesigner 2.0.3 software show that the proposed decoders perform well. Comparisons show that the proposed 2‐to‐4 QCA decoder is superior to the previously proposed ones in terms of cell count, occupied area, and delay.
