3. For a n-Channel JFET CS
amplifier circuit with the following values:
VDD=16V,
RL =12 kΩ, R1 =
70kΩ, R2 = 50
kΩ, RD =
5kΩ, RSS = 2 kΩ, Source
internal
resistance Rs =
200Ω.
Assume IDSS= 14mA, Vp = -4V and
RSS is fully
bypassed.
b. Find the ac
voltage gain Av and the input impedance Zi
c. Draw the ac
equivalent circuit using an ac model
amplifier circuit with the following values:
