46.8.1. Recap of Covered Topics

Try these first

1. 1.

   What is voltage gain?

   Hint

   Think of how much the input signal is amplified.

2. 2.

   Why should input resistance be high?

   Hint

   Consider how signals travel in a circuit.

3. 3.

   What is the primary purpose of a common collector amplifier?

   • Voltage amplification
   • Impedance matching
   • Signal distortion

   Hint

   Consider what characteristics it optimizes.

4. 4.

   True or False: The output resistance of a common collector amplifier is typically low.

   • True
   • False

   Hint

   Link it to power transfer efficiency.

5. 5.

   Design a common collector amplifier for a scenario where you need to drive a load of 10kΩ with a high input resistance. Discuss the trade-offs involved.

   Hint

   Consider how input and output resistances interplay.

6. 6.

   Evaluate the influence of unwanted capacitance due to PCB layout in a high-frequency design of a common collector amplifier.

   Hint

   Reflect on the physical layout considerations.
