Nikoli Tuesday, May 8, 2007. 3:40-5:00pm EE241SPRING 2007: FINAL EXAM NAME Last First GRAD/UNDERGRAD Problem 1: Problem 2: Total: EE241: SPRING 2007 FINAL EXAM 2/7 PROBLEM 1. (20 pts) Adders. In this problem, we will examine some properties of carry-lookahead adders. a) (5pts) Conventional generate equation for a 4-bit group, from bit position 0 to bit position 3 is given by: 1 2 3 1 2 3 2 3 3 : 3 g p p p g p p g p g G + + + = . If this equation is used to compute G 3:0 from primary inputs a , b , a 1 , b 1 , a 2 , b 2 , a 3 , b 3 , what would be the tallest stack of NMOS devices in a footless domino implementation of this gate? EE241: SPRING 2007 FINAL EXAM 3/7 b) (5 pts) Starting with the conventional generate equation for a 4-bit group: 1 2 3 1 2 3 2 3 3 : 3 g p p p g p p g p g G + + + = , derive the equation for the Lings...
