   Hint

   Think about what part of the transistor circuit connects input and output.

2. 2.

   Name one key feature of a common emitter configuration.

   Hint

   Consider voltage vs. current in signal amplification.

3. 3.

   What is the main advantage of a common collector configuration?

   • High Voltage Gain
   • High Input Resistance
   • High Output Resistance

   Hint

   Think about the purpose of the configuration.

4. 4.

   True or False: The output resistance of a common emitter configuration is high.

   • True
   • False

   Hint

   Recall the characteristics of the CE setup.

5. 5.

   Design a circuit using a composite transistor to achieve a specific gain. What considerations must be taken for biasing and load?

   Hint

   Ensure to calculate each stage’s gain and consider how they affect each other.

6. 6.

   Explain the effect of temperature variations on the performance of a composite transistor configuration. How would you mitigate these effects?

   Hint

   Consider how temperature affects electron mobility in the transistors.
