43.3.3. Configuration Discussion

Try these first

1. 1.

   What is a key feature needed for voltage mode buffers?

   Hint

   Consider what would be preferable to avoid signal loss.

2. 2.

   Name a configuration used for current mode buffers.

   Hint

   Think about the ways to categorize BJTs and MOSFETs.

3. 3.

   What is the ideal output resistance for voltage mode buffers?

   • High
   • Low
   • Medium

   Hint

   Think about what keeps the output robust.

4. 4.

   True or False: Current mode buffers require high input resistance.

   • True
   • False

   Hint

   Reflect on how loading affects current flow.

5. 5.

   Design a cascading circuit with both voltage and current mode buffers. Explain your choice of configurations and their associated features.

   Hint

   Think about how buffers interact in both modes and why their characteristics matter.

6. 6.

   Evaluate the performance of a common drain configuration in a high-frequency amplifier application. What challenges might arise?

   Hint

   Consider the frequency response in relation to capacitance and resistance.
