Try these first

1. 1.

   What is the main advantage of a Common Collector configuration?

   Hint

   Think about the resistance seen from the input side.

2. 2.

   What does cascading a CE stage with a CC stage accomplish?

   Hint

   Recall the functions of each stage individually.

3. 3.

   What does a CC stage primarily enhance in a transistor amplifier?

   • Input Resistance
   • Output Resistance
   • Voltage Gain

   Hint

   Think about what makes this configuration different.

4. 4.

   True or False: The main purpose of cascading CC stages is to increase output voltage.

   • True
   • False

   Hint

   Reflect on what output voltage signifies in amplifier design.

5. 5.

   You have to design a multi-transistor amplifier using CE and CC configurations. Describe how you will enhance input resistance and maintain low output resistance. Outline the circuit diagram as well.

   Hint

   Consider the relationship between the stages and which resistor values will aid in achieving your goals.

6. 6.

   Analyze a given circuit with two cascaded transistor stages. Calculate the overall voltage gain and comment on the significance of each stage's performance metrics.

   Hint

   How do you calculate voltage gain from each individual transistor?
