Challenge Problems
Push your limits with challenges.
Question 1
You have a JFET with IDSS of 3mA and a pinch-off voltage VP of -2V. Calculate the gate-source voltage (VGS) needed to establish a drain current of 1.5mA.
💡 Hint: Isolate VGS from the equation and solve accordingly.
Question 2
Design a JFET self-bias circuit for a drain current of 2mA, knowing IDSS = 4mA and VP = -1V. Provide all calculations.
💡 Hint: Follow the steps discussed in class for consistency and use the provided formulas carefully.
