Suggest one way of sizing the transistors of the logic

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....
