Assume that all output capacitances are lumped together into a single load capacitance CL = 45fF. You may ignore all intermediate (internal) capacitances for this part. (c) Calculate the fastest high-to-low propagation delay. CL = 45fF. You may ignore all intermediate (internal) capacitances for this part. (d) What are the input patterns that give the worst-case tpHL and tpLH. State clearly what the initial input patterns are and which input(s) has to make a transition in order to achieve this maximum propagation delay. Consider the effect of the capacitances at the internal nodes for part (d).
