Challenge Problems
Push your limits with challenges.
Question 1
Given a JFET with IDSS = 3mA and VP = -2V, design a self-bias circuit to stabilize at a drain current of 1.5mA.
💡 Hint: Start from calculating VGS first, apply it to find RS, then use ID to solve for RD.
Question 2
If the temperature rises causing ID to go up from 1.5mA to 2.5mA, determine the effect on VGS and discuss how the self-bias circuit responds.
💡 Hint: Refer back to the principle of negative feedback and its effect on self-regulation.
