43.3. Conclusions

Try these first

1. 1.

   What should the output resistance be in a voltage mode amplifier?

   Hint

   Think about how loading affects performance.

2. 2.

   What type of configuration is used for a voltage mode buffer in BJTs?

   Hint

   Recall the specific name of the configuration.

3. 3.

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

   • High
   • Low
   • Moderate

   Hint

   Consider how it affects signal transfer.

4. 4.

   In current mode amplifiers, what is the desired input resistance?

   • True
   • False

   Hint

   Opposite to what you see in voltage mode.

5. 5.

   Design a hybrid amplifier that combines both current and voltage modes. Discuss how buffers will interact and what features are most critical.

   Hint

   Think about how these two modes can complement each other.

6. 6.

   Evaluate how increasing the input capacitance in a voltage mode system might impact overall performance and signal integrity.

   Hint

   Consider the consequences on the frequency response.
