57.3.9. Common Source followed by Common Gate Configuration

Try these first

1. 1.

   What is a common emitter configuration?

   Hint

   Think about what part of the transistor is 'common'.

2. 2.

   Explain why CC configuration is known as an emitter follower.

   Hint

   Compare the output and input voltages.

3. 3.

   What is the main advantage of using a common collector configuration?

   • High voltage gain
   • Low input impedance
   • High input impedance

   Hint

   Remember why we use emitter followers.

4. 4.

   The transconductance of a transistor is defined as:

   • True
   • False

   Hint

   Reflect on the definitions discussed in class.

5. 5.

   Design a multi-stage amplifier using one CE configuration followed by a CC configuration. Calculate the voltage gain and discuss how input and output impedances will change.

   Hint

   Focus on applying derived equations effectively.

6. 6.

   Explain how incorporating a common gate configuration after a common source may change the performance parameters.

   Hint

   Consider the interaction between the gain characteristics of both configurations.
