Modeling an Improved Modified Type in Metallic Quantum-Dot Fixed Cell for Nano Structure Implementation
Samira Sayedsalehi, Arman Roohi · 2015
Quantum-dot cellular automata (QCA) is a transistor-less computation approach which encodes binary information via configuration of charges among quantum dots. The fundamental QCA logic primitives are the majority gate and the inverter gate which can be employed to design various QCA circuits. In this study by applying some fixed predefined level of polarization, a detailed modeling of a modified type of fixed metal-dots QCA cell will be explored. An efficient architecture controlled by predefined polarization of fixed cells that position next to the input cells is presented for implementing a desired nano structure. The efficiency of the proposed approach is verified by implementing of several important examples of Boolean function.
