50.3. Summary of Discussion

Try these first

1. 1.

   What does the term 'unloaded conditions' mean in amplifier circuits?

   Hint

   Think about how we observe the output current while preventing any load.

2. 2.

   What parameter does g_m represent?

   Hint

   Consider how a small voltage change can affect currents.

3. 3.

   What happens when the output terminal of a common base amplifier is unloaded?

   • True
   • False

   Hint

   Remember the definition of unloaded conditions.

4. 4.

   Current gain in a common gate configuration approaches which value?

   • 0
   • 1
   • Infinity

   Hint

   Think about how amplifiers work!

5. 5.

   Design a common base amplifier for a given current gain of 50. What specifications would you consider?

   Hint

   Think about what factors influence the payoff for gains.

6. 6.

   Compare the phase shift in a common base versus a common gate amplifier. How does this impact circuit design?

   Hint

   Consider the implications of phase shifts in signal synchronization.
