Figure 1: Question 1

A
Compute the following DC parameters
(i) I_E
(ii) V_E
(iii) V_B
(iv) I_C
(v) V_C
(vi) V_CE
(Hint: Note the voltage divider is not stiff, so do not assume IB is negligible.)

B
Compute the following AC parameters
(i) R_in(base)
(ii) R_in(tot)
(iii) A_v
(iv) Compute the overall gain Ajv when a signal source with a resistance of 1.6 k? is connected to the amplifier.

C What is the theoretical minimum value for C2 if the amplifier must operate over a frequency range from 1 kHz to 5 kHz?

Question 2
For the self biased JFET circuit in Figure (2), given that ID = 1.2mA, compute:
(a) VDS
(b) VGS
