56.5. Lecture – 56

Try these first

1. 1.

   What is the primary characteristic of a CC configuration?

   Hint

   Think about why we would use this configuration.

2. 2.

   What does biasing do in a transistor circuit?

   Hint

   Consider how the transistor needs to operate in a certain range.

3. 3.

   What is the primary advantage of using a Common Collector configuration?

   • High input resistance
   • High output resistance
   • Low gain

   Hint

   Think about what you want to avoid when driving a signal.

4. 4.

   True or False: The Common Emitter configuration provides high current gain.

   • True
   • False

   Hint

   Consider what happens when you apply a small input signal.

5. 5.

   If a composite transistor includes a CC followed by a CE, how will the overall input resistance compare to standalone configurations?

   Hint

   Consider how the input characteristics of each configuration interact.

6. 6.

   Design a circuit incorporating both CE and CC stages aimed at maximizing bandwidth.

   Hint

   Pay attention to the biasing schemes to keep distortion minimal while maximizing bandwidth.
