Homework Help: Suggest one way of sizing the transistors of the logic

  1. Mar 28, 2015 #1
    1. The problem statement, all variables and given/known data
    Suggest one way of sizing the transistors of the logic circuit such that its worst case
    tpHL equals the tpHL of an inverter with a sizing of (W/L)min.

    2. Relevant equations
    I think the only equation is the (W/L) itself.

    3. The attempt at a solution
    I have actually done the front part of the question and I got the worst case ratio to be 3. But I am not too sure about the theory part to suggest a way. Anyone help?

    I probably can't help with the question, but I wonder how you got "3" without any numbers given in the problem statement.
