44.2.1. Course Overview

Try these first

1. 1.

   Define a common collector amplifier.

   Hint

   Think about what it ideally does to the input signal.

2. 2.

   What is meant by voltage gain?

   Hint

   Focus on the output behavior related to the input.

3. 3.

   What is a primary function of a common collector amplifier?

   • To decrease input impedance
   • To improve signal quality
   • To amplify current

   Hint

   Think about what happens at the output when connected to a next stage.

4. 4.

   In a common drain amplifier, the output voltage is expected to:

   • True
   • False

   Hint

   Consider the forwarding nature of the configuration.

5. 5.

   Design a common collector amplifier that could compensate for an input signal varying between 1V to 3V while keeping output variance minimal. Provide calculations for biasing.

   Hint

   Consider the necessary voltage divider setup for optimal bias.

6. 6.

   Given a circuit with a common drain amplifier, analyze how changes in the load resistance will affect the output voltage. Develop a formula to show this dependence.

   Hint

   Start from the basic relationships of current and resistance in the circuit.
