Question 1

What does the cutoff frequency refer to?

  • The maximum frequency
  • The frequency with output reduction
  • Frequency at signal gain is 100%

💡 Hint: Think of where effective amplification starts to drop.

Question 2

True or False: The DC voltage at the drain should be set above the threshold voltage for effective amplification.

  • True
  • False

💡 Hint: What happens to the transistor if it operates below threshold?

Challenge Problems

Push your limits with challenges.

Question 1

Given a transistor with a threshold voltage of 0.7V and you want to design a circuit for a 1.5V DC output swing, determine the resistor values needed for a stable operation.

💡 Hint: Balance is essential — think about how much voltage you need on either side.

Question 2

Design an amplifier with a maximum gain of 20 while drawing a 1mA load current. Calculate both the necessary resistor values and the biasing current.

💡 Hint: Think about how gain relates to component values in achieving desired performance.
