Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for calculating the voltage gain in a common emitter amplifier?
- Av = -g_m / R_C
- Av = -g_m * R_C
- Av = g_m + R_C
💡 Hint: Remember the signs and relationship of gain to resistance.
Question 2
True or False: The output swing of an amplifier can be increased by reducing the supply voltage.
- True
- False
💡 Hint: Think about what happens to voltage levels.
