[SOLVED] [Moved]: Low Frequency FET Amplifier exercise

Hey guys, I am having trouble solving a couple of homework exercises, I would really appreciate if you helped me understand the following exercises:

Exercise 1
Design a low frequency amplifier with two cascoding states, using the model with respective parameters: h_ie= 4 kΩ and h_fe=200
First state: Voltage divisor resistance R₁= 100kΩ , R₂=10kΩ
Output resistance R_C1= 10 kΩ
Second state:Voltage divisor resistance R₁= 45kΩ , R₂=5kΩ
Output resistance R_C2= 3 kΩ
As for the input the signal source V_s with R_s=1kΩ is applied
Find A_I,A_IS,A_V,A_VS,R_i,R_o and R_o'


Exercise 2
Design a low frequency FET amplifier considering R_d=5kΩ , R_s=0.5kΩ and R_g 1 MΩ. V_DD applied is 30 V
Find the I_D and g_m values for the default configuration.
Find the voltage amplifier expression A_VS
Hint: consider I_D=16(1+V_GS/4)²
This excercise is also accompanied by the attached image.

Please help me out if you can to understand how to solve these exercises quickly and sorry for the bad english, the exercises were translated from another language.

Didn't you learn about transistors and how to design an amplifier with them in school or in university and weren't you taught it by a teacher? Or did you skip all the classes and you want somebody here to do your homework for you?
