Design and Implementation of Hybrid Full Adder-Based Ripple Carry Adder for Low Power Applications
Year: 2025
Type: article
Abstract: Full adders are fundamental components in various applications, including Digital Signal Processors (DSPs) and microprocessors. In modern circuit design, reducing supply voltage has become a key approach to minimizing energy consumption. Since the full adder serves as a primary arithmetic unit in many computational tasks, it plays a crucial role in the efficiency of the Arithmetic Logic Unit (ALU). This project introduces novel hybrid full adder designs aimed at achieving low Power-Delay Product (PDP). Additionally, a Ripple Carry Adder (RCA) is proposed using a chain structure to enhance driving strength. The hybrid full adder topologies are implemented to construct a 4-bit RCA based on CMOS technology, optimizing power and performance.
