Design & Development of Multipliers & Square Circuits Using the Concepts of Quantum-Dot Cellular Automata (QCA) Technology

Quantum dots Cellular Automatas [QCA] represents an groundbreaking advancement in nanoelectronics, characterizeed by their lower power consumptions, higher-speed operations, & enhanced integration capabilities. These attributes position QCA as a formidable contender to the prevalent Complementery Metal-Oxides-Semiconductors (CMOS) technology, which are currently the industry standard. The focus of these researches is on the innovative design of a QCA-based Multiplier and Square circuit. Multipliers are integral to various digital signal processing applications, where they significantly influence system throughput and power efficiency. Square circuits, on the other hand, are vital for performing mathematical computations. The design of the QCA-based multiplier incorporates binary adders and AND gates, optimizing it for efficient performance. To thoroughly assess the viability of QCA over traditional CMOS, a comparative analysis focusing on key metrics in the areas utilization & thier power's dissipations is undertaken. Their QCA Designer tool plays a critical role in this evaluation, allowing for the validation of the proposed model by examining parameters like cell count, area, and energy dissipation. This approach not only highlights the potential enhancements QCA offers over CMOS but, it further gives the router for a no. of future scope in innovations w.r.t. nanoelectronics.
