Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for voltage gain in an amplifier?
- A_v = v_out / v_in
- A_v = v_in / v_out
- A_v = v_out + v_in
💡 Hint: Focus on what the gain is intended to show.
Question 2
True or False: Higher input resistance is always desirable for an amplifier.
- True
- False
💡 Hint: Consider the implications of loading on inputs.

Challenge Problems
Push your limits with challenges.
Question 1
You need to design a common emitter amplifier that achieves a voltage gain of -50 with an input resistance of at least 20 kΩ. What steps will you take?
💡 Hint: Consider using multiple configurations to check interdependencies.
Question 2
A common source FET amplifier has V_GS = 2V, with a transconductance of 5 mS and an output resistance of 1 kΩ. Calculate the expected output voltage given an input signal of 0.1V.
💡 Hint: Break down the formula first to find each component's interaction.
