Below is question 2 part b with the answer

2. (40 points) Consider extending the idea of the comparator circuit described in the Application Activity of Class 23 tRAT and AA from 4 bits to 8 bits. (You do not need to draw the circuit diagram.) (a) (10 points) Based on the answer of Homework #6 Class 17 Question 2 part b), how many transistors are required to implement the ripple-carry adder used in the 8-bit comparator? (20 points) Besides the gates used in the ripple-carry adder, list the gates with the number of inputs required for the 8-bit comparator. (10 points) How many transistors are required to implement the 8-bit comparator with this approach? (b) (c)

Explanation / Answer

2input AND gate reqires 3 transistors

2inpu OR gate requires 3 transistors

2input X OR requires 10 transistors

Si total is 10+10+3+3+3=29
