60.1.1. CC followed by CE Amplifier

Try these first

1. 1.

   What is the primary function of a common collector stage?

   Hint

   Think about what happens when you connect to a high source resistance.

2. 2.

   What does the CC stage help to reduce in the CE amplifier?

   Hint

   Consider capacitive effects in amplifier configurations.

3. 3.

   What does the common collector stage provide?

   • Low input impedance
   • High input impedance
   • Negative feedback

   Hint

   Think about the input terminals versus output.

4. 4.

   True or False: The emitter current of the CC stage provides biasing directly to the CE stage.

   • True
   • False

   Hint

   This is about the connectivity of the stages.

5. 5.

   Design a CC-CE amplifier circuit that achieves a specific voltage gain while meeting certain input resistance requirements without exceeding maximum current ratings for each transistor. Calculate all biasing currents based on your design.

   Hint

   Plan first, calculate the biasing second.

6. 6.

   Given a set of parameters for a CC-CE amplifier circuit, analyze the expected performance metrics such as input resistance, gain, and stability. Discuss potential design adjustments.

   Hint

   Utilize the concepts learned regarding input impedance and feedback.
