- VGS(off)
💡 Hint: Remember the definition of maximum drain current.
Question 2
True or False: The cut-off voltage is the gate-source voltage at which the drain current stops.
- True
- False
💡 Hint: Think about when the JFET switches off.

Challenge Problems
Push your limits with challenges.
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).
💡 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.
💡 Hint: How does VGS compare to VGS(off)?
