Abstract Unlike previous technologies, QCA does not depend on the movement of electrons in the wire to transmit information. This feature significantly improves the speed of the circuits and reduces the power consumption, which is a great incentive for digital circuit designers to use this technology. In this paper, a new structure of full-adder is proposed, designed, implemented and simulated using two gates that improve the complexity and latency compared to previous designs. Simulation results are obtained using QCADesigner which illustrates the valid performance of the proposed design. The proposed structure has a 30% improvement in the number of cells and a 41% improvement in the occupied area.

摘要 不同于以往的技术，QCA 不依赖于电子在导线中的运动来传递信息。这一特性显着提高了电路的速度并降低了功耗，这是数字电路设计人员使用该技术的极大动力。在本文中，使用两个门提出、设计、实现和模拟了一种新的全加器结构，与以前的设计相比，它提高了复杂性和延迟。仿真结果是使用 QCADesigner 获得的，它说明了所提出设计的有效性能。所提出的结构在单元数量上有 30% 的改进，在占用面积上有 41% 的改进。
