ECE question

  1. Sep 13, 2009 #1
    1. The problem statement, all variables and given/known data

    Different versions of a processor have different dynamic power dissipation. Dissipation also differs with the applied voltage. Version 1 at 0.7V has a dynamic dissipation of 50W and at 1.4V a dynamic dissipation of 100W. Version 2 has a dynamic dissipation of 80W at 1.4V and of 40W at 0.7V.
    (1) If the static to dynamic power ratio is 0.7, what is the static power for the two versions at 0.7V?
    (2) What is the leakage current for each version at 0.7V?



    2. Relevant equations and The attempt at a solution

    For Part 1, i just multiplied .7(ratio) times version 1(.7) power and version 2(.7) power to get the static power

    For part 2, i dont know how to start the problem, i was thinking about using P = VI, where V is .7
