![d)
In Figure 3.3 shows the circuit diagram of a typical n-channel JFET common
source amplifier. If ac input impedance of this amplifier is RGG = 1.XY
Mohm, VGG = 1. XY V, RD= 1.5 x Rs and VDD = 16 V. Determine the value
of Rs to set the Q-point to VGs = -1.5V and lo= 3.5 mA. What is the value
of VDs at the Q-point? Sketch the amplifier's small signal equivalent circuit
model. If the JFET transconductance at this bias point (Q-point) is gm =
2.XY MS and go = 0.01 mS, what is the ac open circuit voltage gain Av and
the ac short circuit current gain A₁ of this amplifier.
