43.3.2. Buffer Features Overview

Try these first

1. 1.

   What should the output resistance be for a voltage mode buffer?

   Hint

   Consider how output resistance affects signal transfer.

2. 2.

   Name the configuration used for voltage mode buffers with BJTs.

   Hint

   Think about the common configurations for BJTs.

3. 3.

   What is the desired input resistance for a voltage mode buffer?

   • Low
   • High
   • Medium

   Hint

   Think about how input resistance affects the overall circuit.

4. 4.

   True or False: A common collector configuration has high output resistance.

   • True
   • False

   Hint

   Recall the key characteristics of the common collector setup.

5. 5.

   Design a circuit using both a voltage mode and a current mode buffer. Specify the components, configurations, and expected results.

   Hint

   Consider the impacts of the chosen buffers on gain and bandwidth.

6. 6.

   Evaluate a given amplifier circuit. If it lacks buffering, discuss the potential signal degradation issues.

   Hint

   Focus on how impedance affects signal integrity in cascaded designs.
