چکیده
Background and Objectives: Quantum-dot Cellular Automata technology is a new method for digital circuits and systems designs. This method can be attractive for researchers due to its special features such as power consumption, high calculation speed and small dimensions.
Methods: This paper tries to design a three-bits counter with minimum area and delay among the other circuits. As the circuit dimensions are reduced, the area and consequently, the delay are decreased, too. Therefore, this paper tries to design a three-bits counter with minimum dimensions and delay. The proposed counter contains 96 cells and is designed in three layers. It has the least area and delay compared to the priors.
Results: The circuit simulation illustrates 0.08 µm2 of area occupation and one clock cycle delay. In comparison with the best previous design, which includes 110 cells, the cells number, area and delay are decreased by 12.72%, 27.27% and 33.33%, respectively. Also, the cost of the circuit has been improved by 54.32%. The power analysis of the design shows 13% reduction in the total energy dissipation of the circuit compared to the best prior work. The circuit reliability versus temperature variations has been simulated and the results represent suitable stability. The fault tolerance of the circuit which is occurred by the displacement faults represents normal operation of the circuit.
Conclusion: As the counter is an element which is implemented in several digital systems, its area reduction causes the whole system area to be reduced. Also, the circuit delay has been decreased significantly which means that the circuit can be employed by high speed systems.
