Design of Low Power and High Speed 4-Bit Ripple Carry Adder Using GDI Multiplexer
Objective
This paper proposes the design of a low power and high-speed 4-bit ripple carry adder (RCA) using the Gate Diffusion Input (GDI) multiplexer.
Abstract
This paper proposes the design of a low power and high-speed 4-bit ripple carry adder (RCA) using the Gate Diffusion Input (GDI) multiplexer. The GDI technique is a well-known method for designing low power digital circuits by reducing the transistor count and power consumption. In this design, the 4-bit RCA is designed using GDI multiplexers and optimized for power and speed. The simulation results show that the proposed RCA design using GDI multiplexers offers a significant reduction in power consumption compared to a conventional RCA design, while maintaining a high-speed performance with a propagation delay. This design can be used in various applications that require low power and high-speed digital circuits.
