Abstract: Quantum-dot cellular automata (QCA) are promising models in nanotechnology based on the single electron effects of quantum dots and molecules. The present study designs and simulates the basic elements or Combinational circuit. A 2-to-4 decoder has been designed and implemented before with the help of numbers of three-input majority voters and successfully implemented in QCA. The design and simulation of a new decoder circuit on QCA with minimum delay, area and complexity we will try to design, simulate and compare with previous designs. The design is optimized by considerably reducing the number of cell counts and QCA wire crossings. The decoder is more robust and enjoys single layer wire crossing, via clock phasing, which requires only one type of cell .we try to implement that the proposed decoder circuit performs equally well compared to existing decoder designs and performs better in case of previous coplanar decoder designs with enable input functionality in all aspects.
We are study and try to design our own circuitry to overcome issue on complex relation for designing a decoder circuit remove or less wire crossing or multi layer option here we understand the last function with help of Boolean function of decoder circuit and realize in single design For This purpose we allow to choose different methodology and design techniques. We have tried to study some of decoder circuit designs on the basis of simulation results to move forward with our own designs for the purpose. QCADesigner software is used to create a detailed layout and for circuit simulation. The circuits simulated using QCADesigner.
