Challenge Problems
Push your limits with advanced challenges
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.
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.
