6 sample questions

Question 1.
What does the drain current (ID) indicate?
Show hintHide hint
Think about what controls the current in a JFET.
Question 2.
What does IDSS represent?
Show hintHide hint
Consider the scenario when no voltage is applied at the gate.
3Question 3.
What is the maximum drain current represented as in JFETs?
- ID
- IDSS
- VGS(off)
Show hintHide hint
Remember the definition of maximum drain current.
4Question 4.
True or False: The cut-off voltage is the gate-source voltage at which the drain current stops.
- True
- False
Show hintHide hint
Think about when the JFET switches off.
Question 5.
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).
Show hintHide hint
Identify how gm relates to required gain and plot bias accordingly.
Question 6.
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.
Show hintHide hint
How does VGS compare to VGS(off)?
