A Novel Quantum-Dot Cellular Automata XOR Design

Abstract:

Quantum-dot cellular automata (QCA) is an emerging nanotechnology that promises faster speed, smaller size, and lower power consumption compared to the transistor-based technology. Moreover, XOR is a useful component for the design of many logical and functional circuits. This paper proposes a novel and efficient QCA XOR design. The proposed XOR design has been compared to a few recent designs in terms of area, speed and complexity. Comparison of results illustrates significant improvements in our design as compared to traditional approaches. Also simulation proves that the proposed XOR design is completely robust and more sustainable to high input frequency as compared to other designs. This robustness is highly significant when this component is applied for realizing larger designs.
