UNIVERSITY OF CALIFORNIA, BERKELEY College of Engineering Department of Electrical Engineering and Computer Sciences Elad Alon Homework #5 EECS141 PROBLEM 1: Logical Effort For this problem, you should assume that C G = 2fF/μm and that the transistors are long- channel for the purpose of calculating LE. a) What is the total path effort from In to Out? b) To minimize the delay, what should the EF/stage for this chain of gates be? c) Size the gates in this chain to minimize the delay from In to Out. Only calculate the input capacitance of the gates; don’t bother to provide the actual transistor sizes. d) Using this sizing, what is the delay (in units of t inv ) of your chain from In rising to Out rising? You can assume that the critical input of the complex gates is always at the “top” of the transistor stacks (i.e., the critical input is always closest to the output node), and that C D /C G = γ = 0.5. e) You present your design to your boss and she tells you that the delay of your circuit is below the specification for the block. She also tells you that your team is over budget on die area. Revise your design such that you save the maximum

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
