Performance Optimization of a 16-Bit Advanced Hybrid Adder

As the demand for low-power, high-performance devices grows and technology advances, the need for efficient digital circuits has increased. Adders, being critical components in arithmetic units, significantly impact the overall performance and resource utilization of digital systems. Traditional Ripple Carry Adders (RCAs) are simple but suffer from linear carry propagation latency, which affects their speed and power efficiency. This paper introduces a 16-bit advanced hybrid adder that combines the simplicity of RCAs with carry look ahead adders to enhance speed and reduce resource consumption. The design and layout of the hybrid adder were created using Cadence Virtuoso for physical design and layout, while Xilinx Vivado was applied to do performance analysis and functional validation .The RTL to GDS synthesis was completed to ensure manufacturability and design integrity, with successful simulation results in Xilinx Vivado confirming functional correctness and performance metrics. The proposed 16-bit hybrid adder demonstrates significant improvements over standard RCAs, including a 72.01% reduction in area, a 2.988% decrease in power consumption, and a 87.46% reduction in cell count. These enhancements make the hybrid adder a valuable choice for modern digital systems that require efficient power and space utilization. The hybrid approach effectively balances simplicity with performance, offering an efficient solution for integrated circuit applications.
