Quantum-Dot Cellular Automata (QCAs) are emerging as a promising alternative to traditional CMOS technology, characterized by their ultralow power consumption, high device density, and fast operation at the nanoscale. Using QCA, a crucial part of Field-Programmable Gate Arrays (FPGAs), we present a novel implementation of the ACTEL ACT 1 logic module in this work. In contrast to traditional CMOS designs, our concept aims to utilize the special advantages of QCA to enhance performance and drastically reduce power consumption. The development of an effective 2-to-1 multiplexer based on QCA majority gates, which serves as the foundation for the ACT 1 module, is a crucial component of our methodology. We successfully leveraged the unique characteristics of QCA to improve key performance metrics by using a hierarchical design approach. Our suggested architecture was designed and simulated using the QCA Designer software. Our simulation findings show that the design achieves a delay of 1.50 clock cycles, uses very little power, and occupies a small area of only 0.24 μm2. These findings demonstrate how the QCA-based ACT 1 module may facilitate the creation of high-performance, ultra-low-power FPGA designs that are ideal for the post-CMOS era.
