Challenge Problems
Push your limits with challenges.
Question 1
Design a self-bias circuit for an N-channel JFET with IDSS = 3mA and VP = -0.5V. If your target ID is 1.5mA, calculate the values for RS and RD needed.
💡 Hint: Work systematically through the equations we've studied.
Question 2
How would you adjust the self-bias circuit parameters to accommodate a change in IDSS from 3mA to 4mA, while maintaining a target ID of 2mA?
💡 Hint: Consider how changes in your original current draw will affect stability.
