Obtain commercially available bipolar transistors and enhancement type n-channel and p-channel MOSFETs for the construction of BiCMOS inverter as shown in Figure 11.18. From the manufacturer’s Web pages, obtain the data sheets for all three types of transistors

1. Using SPICE, estimate the load capacitance, C_L,1000, for which the average propagation delay will be 1000 ns.

2. Using SPICE, determine and plot the average propagation delay as a function of the load capacitance for C_L,₁₀₀₀/10 ≤ C_L
≤ 10C_L,₁₀₀₀.

3. Build a three-stage ring oscillator using these inverter circuits. Measure the average propagation delay as a function of the load capacitance, for C_L,₁₀₀₀/10 ≤ C_L
≤ 10C_L,₁₀₀₀.

4. Plot the SPICE and experimental results on the same graph. Are the characteristic linear? Do the extrapolated characteristics pass through the origin? Explain.
