Question 1

What is the maximum drain current represented as in JFETs?

  • ID
  • IDSS
  • VGS(off)

πŸ’‘ 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

πŸ’‘ 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).

πŸ’‘ 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.

πŸ’‘ Hint: How does VGS compare to VGS(off)?
