An output pad contains a chain successively large inverters to drive the (relatively) enormous off-chip capacitance. If the first inverter in the chain has an input capacitance of 20fF and the off chip load is 10 pF, how many inverters should be used to drive the load with the least delay? Estimate the delay, expressed in F04 inverter delays?
