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?
