Question 1
Design a JFET amplifier with a required gain of 20, given that IDSS is 10 mA and VGS(off) is -4V. Determine the necessary transconductance (gm).
π‘ Hint: Identify how gm relates to required gain and plot bias accordingly.
Question 2
A specific JFET exhibits a cut-off voltage of -2V. If a voltage of -1.5V is applied, discuss the expected behavior of the JFET.
π‘ Hint: How does VGS compare to VGS(off)?
