Time Limit: 1 hour, 15 minutes (pace yourself). Check for 5 pages in exam. Write your work and all your answers in the boxes provided for them. Use the back of the pages for scratch work if needed. State clearly any assumptions made. 1. (20 points) (a) Determine the worst-case charge sharing noise on the output of the N of the dynamic gate below as a function of V DD , when the input is ABCDEF = 111101. Assume that the diffusion capacitance on uncontacted nodes is half the gate capacitance and that on contacted nodes is equal to the gate capacitance. Also assume that all the nMOS transistors are minimum sized and the pMOS transistors are twice the width of the nMOS transistors. V DD (b) What is the worst-case noise over all possible inputs? V DD B C D E F clk A N 1 2. (20 points) Write down the approximate setup time, hold time and clock-to-Q delay in the flip-flop below, in...
