Abstract: (699 Views)
In this paper, an attempt has been made to examine the different structures of the full adder in QCA technology and to introduce a new structure as the full adder in quantum-dot cellular automata (QCA) technology. Previous structures have problems from the point of view of the number of consumed cells and the occupied cross-sectional area. In this article, in addition to reducing the number of cells and delay, the consumed area has also been tried to have a reasonable and small amount. In addition, some structures could not be used in larger circuits due to the placement of inputs or outputs inside the circuit. Therefore, in this paper, the structure of the proposed full adder with only 28 cells, half-cycle clock delay and cross-sectional area of 0.01 µm2 is presented. Then, the mentioned structure is used in a more complex circuit to confirm the correct behavior and operation, and in fact, a ripple carry adder structure is designed. The proposed design has an efficient QCA implementation in terms of complexity, where the simulation is done using the QCAdesigner tool to estimate the performance of the structures.
