Try these first
- 1.
Define a common-emitter amplifier.
Hint
Think about its main purpose.
- 2.
What does g_m represent?
Hint
How efficient is the input voltage transferred to output?
- 3.
What is the primary purpose of a common-emitter amplifier?
- Increase Voltage
- Decrease Current
- Raise Bandwidth
Hint
Think about its role in circuits.
- 4.
True or False: Adding a CC stage always increases voltage gain.
- True
- False
Hint
Consider the definitions of our amplifier criteria.
- 5.
Given a common-emitter amplifier with β = 100, R_C = 1 kΩ and r_o = 25 kΩ, calculate its voltage gain, then add a CC stage with an expected bandwidth increase.
Hint
Use parallel resistance formulas for calculation.
