چکیده :
Adders are essential components in digital systems and are widely studied in various technologies such as Complementary Metal Oxide Semiconductor (CMOS) and Quantumdot Cellular Automata (QCA). Previous research in CMOS has aimed to reduce the critical path delay by using traditional methods such as Carry Select Adder (CSA) and Carry Lookahead Adder (CLA). However, these methods are not effective in QCA technology as the wiring costs increase the latency more than simple Ripple Carry Adders (RCAs). To enhance adder designs, we utilize the distinctive features of QCA technology. In this paper, we focus on arry generation latency as the main factor of latency in adders and introduce novel circuits that operate in ¼ clock cycles and decrease carry generation delay and area. We also design fast adder blocks that achieve 57.9% and 28.0% reductions in delay time and 76.0% and 11.6% in area compared to CLA and RCA design methods, respectively. Our proposed QCA circuit designs demonstrate a considerable improvement over conventional QCA adders by utilizing the unique properties of quantum cells and minimizing delay time in the QCA adder’s critical path.
