A novel design for managing the faults of the 2 × 2 nano-scale crossbar using quantum-dots

Abstract

Due to new challenges in transistor technology, non-traditional design approaches and processes have risen to the fore. Quantum-dot Cellular Automata (QCA) nano-technology is a fascinating design method that uses columbic repulsion to transmit and manipulate data. On the other hand, crossbar circuits are critical areas in digital circuits and a signal across several users. A new design is suggested in this paper for a crossbar circuit to manage the faults and decrease the complexity. This paper creates the fault-tolerant crossbar circuit by combining a fault-tolerant majority gate. The clock zone technique is used to implement the suggested architecture. As a result, the suggested design is less susceptible to manufacturing flaws. In addition, the proposed design can manage energy dissipation efficiently. QCADesigner-E is used for simulation and energy dissipation studies. The suggested fault-tolerant crossbar circuit in QCA nano-technology has only 156 cells and 0.18 µm2 area.
