Exam II, byWilliam Eisenstadt 10/19/2010 Page 2 of 6 ii) (20 points). See the attached layout and circle and label 4 different design rule errors. Each square is 125nm. List the errors and their labels below.
Exam II, byWilliam Eisenstadt 10/19/2010 Page 3 of 6 PROBLEM 2: (40 Points) RC transmission line and capacitance: Look over the diagram of the metal transmission line. Each square is 125nm. Use the capacitance table p. 143 Rabaey and area and fringe capacitance calculations. Assume the resistance of one segment of the metal line from C to C in is: R = 0.07 * (1 + 1 + (2X + 4)/4 + 1): X 0 R= 0.07 *(1 +1): X = 0 i) (10 points). The goal is to make a delay line for our digital circuit. For a standard transmission line x = 0. What pair of metal conductors (Al1, Al2, Al3
