Question 1

What is the main goal of setting the DC operating point in amplifier design?

  • To ensure maximum output swing
  • To reduce power loss
  • To ensure lower current
  • To make the amplifier more complex

💡 Hint: Consider the implications of adjusting this point in terms of swing.

Question 2

True or False: The gain of a common source amplifier depends on both transconductance and load resistance.

  • True
  • False

💡 Hint: Recall how gain is formulated.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
