Figure E10.18 shows a 2.5 V LVCMOS insertion. In (a), it feeds a pull-up carry RL, conjuncture in (b) it feeds a pull-down carry RL. Assume that VDD is precisely 2.5 V. Using the parameters absorbed for this I/O in Figure 10.23, retort the questions under.

a. Estimate the insufficiency estimate of RL in (a) such that the voltage at node y, when y = '0', is not surpassing than 0.4 V.

b. Estimate the insufficiency estimate of RL in (b) such that the voltage at node y, when y = '1', is not inferior than 2 V.

c. In (a) and (b) aloft is it essential to fir a proviso for the completion estimate of RL? Explain.
