59.3.3. Output Resistance of the CC Stage

Try these first

1. 1.

   What is the primary function of a common collector stage?

   Hint

   Think about how it interfaces different circuit stages.

2. 2.

   What formula represents the output resistance of the CC stage?

   Hint

   Consider the contributions of resistances in the circuit.

3. 3.

   What is the primary characteristic of a common collector amplifier?

   • Provides low input impedance
   • Provides high input impedance
   • No effect on impedance

   Hint

   Think about its role in connecting stages.

4. 4.

   True or False: The output resistance of a CC stage is typically low.

   • True
   • False

   Hint

   Recall the definitions related to the output characteristics.

5. 5.

   Design a CC stage to interface between a high impedance sensor and a low impedance load. Calculate the necessary component values.

   Hint

   Consider the input and output impedance needs and how they relate.

6. 6.

   Analyze the effects of varying load capacitance on the frequency response of a CC stage amplifier.

   Hint

   Use the relationship in the RC circuits to find frequency responses.
