Question: Question 1 A 1 6 - bit carry propagation adder ( CPA ) is shown in Figure 1 a . It is built from 1

Question 1
A 16-bit carry propagation adder (CPA) is shown in Figure 1a. It is built from 16 identical 1-bit (FA) adders. This CPA adder is redesigned with 4 identical 4-bit Carry-Look-Ahead (CLA) adders (CLAs) as shown in Figure lb.
a. Calculate the total number of transistors necessary to implement each of the adder of Figure la and Figure lb.
b. Calculate the speed ratio (CLA/CPA) between the two adders.
