[attachment=47616]

Implementations of Multi-bit Adders:

1. Ripple Carry Adder
2. Carry Lookahead Adder

Ripple Carry Adder

n-bit Ripple Carry Adder
Composed of n 1-bit Full Adders
Carries ripple from LSB stage to MSB stage
Delay ~ (n)*(delay of single FA stage)
Area required is linear in n
4-bit Ripple Carry Adder
Composed of 4 1-bit Full Adders
