60.1. Multi-Transistor Amplifiers (Contd.): Numerical Examples (Part C)

Try these first

1. 1.

   What does a common collector amplifier do?

   Hint

   Think about its role in stabilizing the voltage.

2. 2.

   How does the mutual biasing simplify circuit design?

   Hint

   Consider how one aids the other.

3. 3.

   What do CC amplifiers primarily provide?

   • Voltage Gain
   • Current Gain
   • Voltage Buffering

   Hint

   Think of their role in managing voltages.

4. 4.

   True or False: A Darlington pair decreases the input resistance compared to a single transistor configuration.

   • True
   • False

   Hint

   What does increasing gain imply for resistance?

5. 5.

   Design a CC-CE amplifier configuration, specifying all relevant resistances and currents. Provide a detailed biasing calculation.

   Hint

   Refer back to the numerical examples for guidance.

6. 6.

   Evaluate the impact of adding a CC stage on an existing CE amplifier. What would be the numerical changes in input resistance?

   Hint

   Think about how input resistances in parallel affect overall totals.
