Question:
For the source-follower network of Fig. 8.91 :
a. Determine AvNL, Zi, and Zo.
b. Sketch the two-port model of Fig. 5.75 with the parameters determined in part (a) in place.
c. Determine AvL and Avs.
d. Change R L to 4.7 kΩ and calculate AvL and Avs. What was the effect of increasing levels of RL on both voltage gains?
e. Change Rsig to 20 kΩ (with RL at 2.2 kΩ) and calculate AvL and Avs. What was the effect of increasing levels of Rsig on both voltage gains?
f. Change R L to 4.7 k and R sig to 20 kΩ and calculate Zi and Zo . What was the effect on both impedance parameters?

As a tutor, I have gained extensive hands-on experience working with students one-on-one and in small group settings. I have developed the ability to effectively assess my students' strengths and weaknesses, and to customize my teaching approach to meet their individual needs.
I am proficient at breaking down complex concepts into simpler, more digestible pieces, and at using a variety of teaching methods (such as visual aids, examples, and interactive exercises) to engage my students and help them understand and retain the material.
I have also gained a lot of experience in providing feedback and guidance to my students, helping them to develop their problem-solving skills and to become more independent learners. Overall, my hands-on experience as a tutor has given me a deep understanding of how to effectively support and encourage students in their learning journey.
