A Review of Quantum Dot Cellular Automata for High Speed Applications

Abstract

In the field of nanotechnology, quantum dot-cellular automata (QCA) is the promising model that can give an elective answer for customary complementary metal oxide semiconductor (CMOS) circuit. Reversible logic and quantum dot cellular automata together can be considered as the most encouraging advances for group of people future generation computers. Quantum Dot Cellular Automata (QCA) is a nanotechnology with numerous appealing highlights like higher speed, more modest size, higher exchanging recurrence, higher scale joining and power consumption. Accordingly, it is utilized for making all assortments of memory. . It is likewise a possible innovation for low power and high-thickness memory plans. Huge memory plans in QCA show extraordinary highlights in light of their compositional design. In QCA-based models, memory should be kept up moving, i.e., the memory state must be ceaselessly traveled through a bunch of QCA cells. Counter circuits as one of the significant circuits in the advanced frameworks are made out of certain hooks, which are associated with one another in arrangement and really they include input beats in the circuit. In QCA-based designs, memory should be kept up moving, i.e., the memory state must be consistently traveled through a bunch of QCA cells. These designs have various highlights, for example, the quantity of pieces put away in a circle, access type (chronic or equal) and cell game plan for the memory bank which is utilized for high speed applications.
