Challenge Problems
Push your limits with advanced challenges
Determine the values of R1 and R2 given that the desired gate voltage is 2V from a 15V supply and current is 1 mA. Note the threshold voltage is 1V. Show all work.
💡 Hint: Remember to outline the impact of V_th on your calculations.
If the threshold voltage of a transistor is 1.5V and you need the output swing of 5V with a supply voltage of 10V, what should the target DC voltage at the drain node be? Calculate and explain how to achieve this.
💡 Hint: Consider how the output swing relates directly to the drain voltage.
