Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Propose a circuit using a JFET self-bias scheme to achieve an ID of 1.5 mA. Outline the design steps and justify your choices.

💡 Hint: Ensure you're looking at both ID and the necessary voltage drops across resistors.

Challenge 2 Hard

Using the given IDSS of 3 mA and VP of -1.5 V for a JFET, derive VGS when you want ID to be 1.2 mA and explain the implications for Q-point design.

💡 Hint: This applies directly into how ID scales with VGS in your designs.
