34.1.7. Performance Parameters Discussion

Try these first

1. 1.

   What is a common source amplifier?

   Hint

   Think about how it functions in a circuit.

2. 2.

   Define DC Operating Point.

   Hint

   Consider its significance for achieving the expected performance.

3. 3.

   What is the purpose of setting the DC operating point in a common source amplifier?

   • True
   • False

   Hint

   Reflect on its importance in signal amplification.

4. 4.

   Gain can be expressed as a function of which two parameters primarily?

   • Input Resistance and Frequency
   • Transconductance and Load Resistance
   • Supply Voltage and Current

   Hint

   Consider the definition of gain.

5. 5.

   Design a common source amplifier that operates effectively with an input signal of 1V peak-to-peak. Assume you have a supply of 12V and a target gain of 10. What are the resistor values you should use?

   Hint

   Break the problem into steps focusing on DC point, then gain.

6. 6.

   Consider a circuit with a MOSFET rated at 0.7mA/V for transconductance. If you wanted to redesign for an output swing of 4V around a midpoint of 6V using supply voltage of 12V, what should the new resistor values be?

   Hint

   Remember to ensure the output voltage stays within the supply limits.
