Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a circuit using a JFET in the ohmic region integrated with a variable resistor and analyze how the circuit would behave if V_GS changes.

💡 Hint: Label the changes in behavior alongside Ohmic characteristics.

Challenge 2 Hard

Given a specific JFET with characteristics, calculate the values of V_GS and V_DS needed to operate in all three regions, and explain the implications of each state.

💡 Hint: Remember to align calculations with the definitions of the regions.
