1. 1.

   What does setting the DC bias to zero achieve in the small signal analysis?

   Hint

   Think about how this affects AC signal analysis.

2. 2.

   Define transconductance (g_m).

   Hint

   Consider its role in amplifying signals.

3. 3.

   What is the role of transconductance in amplifiers?

   • Controls voltage gain
   • Defines input resistance
   • Influences output capacitance

   Hint

   Think about its definition and how it interacts with voltage and current.

4. 4.

   True or False: The output resistance of a Common Source Amplifier typically has a low value.

   • True
   • False

   Hint

   Consider the interactions with connected circuits.

5. 5.

   Design a Common Source Amplifier to achieve a voltage gain of -10 with specified R_D and transconductance. Discuss parameters affecting performance.

   Hint

   Focus on balancing R values against desired gain factors.

6. 6.

   Evaluate how increasing load resistance affects the overall behavior of the Common Source Amplifier.

   Hint

   Think about voltage division principles.
