54.3.1. Design Guidelines

Try these first

1. 1.

   What is the minimum voltage drop required for an output swing of ±4V?

   Hint

   Consider the positive and negative swings.

2. 2.

   What term describes how much the output voltage is amplified compared to the input voltage?

   Hint

   Think about what it tells about the amplifier’s performance.

3. 3.

   What should the output swing not exceed?

   • The supply voltage
   • The input voltage
   • The gate voltage

   Hint

   Think about the limits of power supply.

4. 4.

   True or False: The input impedance can be significantly higher than the output impedance to improve current gain.

   • True
   • False

   Hint

   Reflect on how impedance matching influences current flow.

5. 5.

   Design a common gate amplifier for a specified output swing of ±5V with a 15V power supply. Calculate appropriate resistor values to meet this requirement.

   Hint

   Pay attention to each step of voltage and resistor calculation.

6. 6.

   Given a common base amplifier with a target gain of 12 and an input impedance of 2kΩ, describe the steps and calculations to determine the necessary component values.

   Hint

   Remember to use gain formulas and test for matching impedances.
