For the self-bias JFET network of Fig. 8.90:

a. Determine A_vNL, Z_i, and Z_o.

b. Sketch the two-port model of Fig. 5.75 with the parameters determined in part (a) in place.

c. Determine A_vL and A_vs.

d. Change R_sig to 10 kΩ and calculate the new levels of A_vL and A_vs. How is the voltage gain affected by an increase in R_s ?

e. For the change of part (d), determine Z_i and Z_o. What was the effect on both impedances?
