Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the exact Q-point for a BJT using specific resistor values for a Fixed Bias arrangement. If rainy weather causes immediate cooling in the environment, how might you expect the Q-point to change?

💡 Hint: Use RB and RC values to find IC and VCE.

Challenge 2 Hard

Using varying JFET parameters, derive the self-bias condition and demonstrate how to maintain the Q-point stable with temperature changes impacting IDSS.

💡 Hint: Refer to the impact of changes in the environment on parameters.
