Consider CMOS circuitry driving a 50-pF off-chip load as illustrated in Figure 9.74. t_ox
= 11 nm. V_T
= 0.5 V.

1. Determine the minimum number of buffer stages necessary such that t_P

2. For each buffer stage, determine the required gate dimensions for each of the MOSFETs.

3. Use SPICE to verify your design.
