Try these first

1. 1.

   What is the primary purpose of using a common collector configuration?

   Hint

   Think about input dynamics.

2. 2.

   Why is biasing necessary in transistor circuits?

   Hint

   Consider the importance of currents.

3. 3.

   What is the main advantage of using common collector configurations?

   • High Voltage Gain
   • High Input Resistance
   • Low Current Gain

   Hint

   Remember the characteristics of the CC stage.

4. 4.

   True or False: Common Emitter configurations are primarily designed to reduce output resistance.

   • True
   • False

   Hint

   Consider the role of CE in amplification.

5. 5.

   Consider a circuit with a CE stage followed by a CC stage. Given the input impedance values and small-signal parameters, calculate the total input resistance.

   Hint

   Combine the resistances effectively based on the configurations used.

6. 6.

   If the upper cutoff frequency of a CE amplifier is found to be 1KHz, how would cascading a CC change this frequency?

   Hint

   Relate the frequency response changes to resistance alterations.
