44.5.2. Comparison of Gain and Resistance

Try these first

1. 1.

   What is the primary benefit of using a common collector amplifier?

   Hint

   Think about loading effects when cascading amplifiers.

2. 2.

   Define loading effect in amplification.

   Hint

   Consider how impedance interacts in circuits.

3. 3.

   What is the typical voltage gain of a common collector amplifier?

   • 0
   • 1
   • Greater than 1

   Hint

   Consider what 'common collector' means regarding signal preservation.

4. 4.

   True or False: Common drain amplifiers are designed for high output resistance.

   • True
   • False

   Hint

   Reflect on the operational design purposes.

5. 5.

   Calculate the input resistance for a common collector amplifier with a given β of 100 and a collector resistance of 1 kΩ.

   Hint

   Use the formula involving β and resistor values from the configuration.

6. 6.

   In a cascading amplifier system using common drain and common collector configurations, how would you determine the overall voltage gain when insensitive to loading?

   Hint

   Consider the effect of each stage independently.
