For the common-base network of Fig. 5.173:
a. Determine Zi Zo" and AvNL.
b. Sketch the two-port model of Fig. 5.63 with the parameters of part (a) in place.
c. Determine AVL and AVs.
d. Determine AVL and AVs using the re model and compare with the results of part (c).
e. Change RS to 0.5 kΩ and RL to 2.2 kΩ and calculate AVL and AVs. What is the effect of changing levels of RS and RL on the voltage gains?
f. Determine Zo if RS changed to 0.5 kΩ with all other parameters as appearing in Fig. 5.173. How is Z0 affected by changing levels of RS?
g. Determine Z, if RL is reduced to 2.2 kΩ. What is the effect of changing levels of RL on the input impedance?
