Try these first

1. 1.

   What are composite transistors?

   Hint

   Think about combining components for easier study.

2. 2.

   What is a key advantage of the Common Collector configuration?

   Hint

   Consider buffering capabilities for signals.

3. 3.

   What is the primary purpose of the Common Collector configuration?

   • To increase voltage gain
   • To provide high input impedance
   • To reduce power loss

   Hint

   Think about the role of CC in amplifier circuits.

4. 4.

   True or False: The voltage gain of a Common Emitter configuration is typically low.

   • True
   • False

   Hint

   Consider how gain is a function of configuration.

5. 5.

   Given a common emitter configuration with a fixed bias and resistor values, calculate the overall input and output resistances.

   Hint

   Use the parallel and series combination rules as applicable.

6. 6.

   Design a Darlington pair to achieve a specified input impedance while maintaining fast-switching characteristics.

   Hint

   Consider trade-offs between speed and impedance when selecting components.
