Robust Coplanar Bus with Unique Modular Design for Quantum-dot Cellular Automata
Objective: The proposed designs have been implemented in order to exploit the properties of Quantum Dot Cellular Automata majority voting to consent a modular robust crossing of wires. Methods/Statistical Analysis: Three structures namely 4x4, 5x5 and 8x8 coplanar buses with unique modular design in quantum dot cellular automata have been presented and the operation of these structures has been tested by QCA Designer Simulation Tool. These unique structures present a modus operandi for designing the modified robust coplanar bus with unique modular approach in nanotechnology. Findings: The proposed modular coplanar structures allow number of coplanar wires to cross without signal degradation and signal loss until information propagates the output. Compared to the reported literature, the proposed design has following advantages; • Unique modular approach in which wires can be intersected on the single layer without any intrusion or crosstalk. • High output polarity, fault tolerant capabilities, modular approach and robustness which makes it more efficient without any interference; • Use of sequential clock which makes it easier to understand and manufacture; • The signal and its counterpart can be simply taken out together due to the alternating polarization. • Proper use of clocking phase pairs in a traversed manner in order to permit the accurate propagation of signals. • Cells are evenly disseminated into the clocking zones which are implemented that the unusable spaces can be as small as feasible. • It has been concluded that it is easy to increase the number of inputs by adding the suitable layers with proposed unique modular approach. Application/Improvements: Starting from lowest number of inputs, it is easy to extend the proposed designs to large and then larger number of inputs by adding suitable layers which will prove efficient to tolerate various faults during the manufacturing process.
