Challenge Problems
Push your limits with challenges.
Question 1
A JFET has IDSS of 15 mA and VGS(off) of -4V. Calculate the drain current (ID) when VGS is -2V using Shockley's equation. Discuss how this affects possible applications.
💡 Hint: Consider substituting the values carefully into the equation and interpreting the results within practical contexts.
Question 2
Design a JFET amplifier circuit that operates in the saturation region. Define key parameters needed to achieve stable amplification.
💡 Hint: Think about common values for ID and VGS and how they influence your circuit's performance.
