Try these first

1. 1.

   What is the main function of a Common Emitter amplifier?

   Hint

   Consider amplification in circuits.

2. 2.

   Define output impedance in your own words.

   Hint

   Think about load-driving capability.

3. 3.

   What is the primary advantage of a Common Emitter amplifier?

   • High voltage gain
   • Low output impedance
   • High input capacitance

   Hint

   Think about what it’s commonly used for.

4. 4.

   True or False: Cascading a CC stage increases voltage gain.

   • True
   • False

   Hint

   Consider the characteristics of each stage.

5. 5.

   Given a circuit design that features a CE and a CC amplifier stage, calculate the expected voltage gain. Assume standard parameters for each stage.

   Hint

   Identify parameters like resistor values for calculation.

6. 6.

   Assess how introducing a Common Base amplifier influences the overall performance when connected after a CE configuration.

   Hint

   Analyze the changes in impedance and overall circuit performance.
