54.3.3. Output Swing Calculation

Try these first

1. 1.

   Define output swing in your own words.

   Hint

   Think about the maximum and minimum voltage levels.

2. 2.

   Why is input impedance important in amplifier design?

   Hint

   Consider how impedance affects voltage and current.

3. 3.

   What does output swing refer to in amplifiers?

   • A. The input voltage range
   • B. The maximum output voltage range
   • C. The overall circuit gain

   Hint

   Think about maximum and minimum voltage output.

4. 4.

   True or False: The input impedance affects how an amplifier connects with its source.

   • True
   • False

   Hint

   Consider why impedance relationships matter.

5. 5.

   Design a common gate amplifier with a supply voltage of 15V. You need an output swing of ±5V. Calculate the minimum necessary values for the resistors considering the output and input requirements.

   Hint

   Start with the requirements of swing first.

6. 6.

   You are given a common gate amplifier needing a peak-to-peak swing of 10V. If the supply is 20V, what voltage drop across the resistors is required, and how do you adjust the input impedance?

   Hint

   Make sure that the swing totals align with your calculations.
