34.1.11. Conclusion and Future Discussion

Try these first

1. 1.

   What is the purpose of biasing a common source amplifier?

   Hint

   Think about the transistor's operation regions.

2. 2.

   What is the typical configuration of a common source amplifier?

   Hint

   Recall the basic setup of a common source circuit.

3. 3.

   What is the purpose of choosing the correct resistor values in a common source amplifier?

   • To avoid heat
   • To maximize gain and output swing
   • To minimize cost

   Hint

   Consider what affects an amplifier's performance.

4. 4.

   True or False: The DC operating point should be set at extremes of the output voltage range.

   • True
   • False

   Hint

   Revisit how swings impact voltage selection.

5. 5.

   Design a common source amplifier for a given target of 1 mA drain current. Use a supply voltage of 15V. Determine the resistor values for R1, R2, and R_D by applying design principles discussed.

   Hint

   Remember to maintain resistor ratios to achieve the desired gate voltage.

6. 6.

   If increasing V_th from 1V to 2V affects the output swing, what practical differences would you need to address in your design?

   Hint

   Investigate how threshold voltage is tied to your operating point.
