43.1.2. Current Mode Circuit Considerations

Try these first

1. 1.

   Define a voltage mode buffer.

   Hint

   Think about the key features outlined in class.

2. 2.

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

   Hint

   Recall the 'little high' part of our mnemonic.

3. 3.

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

   • High
   • Low
   • Medium

   Hint

   Remember our discussion about resistance characteristics.

4. 4.

   True or False: In current mode buffers, the input resistance should be high.

   • True
   • False

   Hint

   Consider the inverse requirement compared to voltage mode.

5. 5.

   You are tasked with designing a dual amplifier circuit that incorporates both voltage and current mode buffers. What configurations would you use, and how would you ensure they meet the necessary specifications?

   Hint

   Think about how to pair configurations efficiently.

6. 6.

   Given a common emitter amplifier experience a 50% gain effect during cascading, how might you modify the circuit using buffers to enhance performance?

   Hint

   Remember our discussions on how buffer placement impacts signal quality.
