Obtain commercially available enhancement type n-channel and p-channel MOSFETs for construction of the rail-to-rail BiCMOS inverter shown in Figure 11.20.

1. Using SPICE, determine the load capacitance, C_L,100, for which the average propagation delay is 100 ns.

2. Build the inverter and apply the load capacitance determined in (1).

3. Apply a 2-MHz square wave input, with a peak to peak amplitude of 5 V and a DC offset of 2.5 V.

4. Measure and plot the slew rate (the slew rate is dV_OUT/dt) vs. V_OUT
for the low-to-high transition.

5. Repeat (4) for the high-to-low transition.

6. Discuss the variation of the slew rate and the practical implications.
