This study demonstrates the development of an innovative $n$-bit less power ripple carry incrementer (RCI) and decrementer (RCD) circuit, respectively, devised using quantum dot cellular automata (QCA). In order to increment or decrement two numbers, RCI and RCD are essential. With a revised configuration of the AND gate, half adder, and XOR gate circuit, the suggested ripple carry incrementer and decrementer circuits are realized. Modern designs for the XOR and half adder are contrasted with these freshly created ones. Circuits are designed using QCA designer 2.0.3. The 4-bit RCI, 8-bit RCI, and 16-bit RCI as well as 4-bit RCD, 8-bit RCD, and 16-bit RCD simulation results are compared to the theoretical findings.

这项研究展示了一种创新的开发$n$分别使用量子点元胞自动机 (QCA) 设计的少位功率纹波进位增量器 (RCI) 和减量器 (RCD) 电路。为了增加或减少两个数字，RCI 和 RCD 是必不可少的。通过修改与门、半加器和异或门电路的配置，实现了建议的纹波进位增量器和减量器电路。XOR 和半加法器的现代设计与这些新创建的设计形成鲜明对比。电路使用QCA Designer 2.0.3 进行设计。将 4 位 RCI、8 位 RCI 和 16 位 RCI 以及 4 位 RCD、8 位 RCD 和 16 位 RCD 仿真结果与理论结果进行比较。
