Designing of Low Power and Efficient 4-Bit Ripple Carry Adder Using GDI Multiplexer

  Vinay K Kolur,  Pavankumar Kulkarni

The low power and less delay ripple carry adder has been proposed in this paper. On the base of GDI multiplexer, 12T full adder is designed. First the architecture of 28T full adder and 12T full adder has been designed. Gate Diffusion Input (GDI) is a current approach in decreasing delay, power consumption and area of digital circuits. Here the performance comparison between 28T based ripple carry adder and 12T based ripple carry adder is presented. Both the designs has been developed and compared. The analysis shows that the 12T GDI based ripple carry adder is better than 28T based ripple carry adder. This work compares the performance of both ripple carry adders in terms of power and delay using 180nm technology.
