54.2.1. Performance Requirements

Try these first

1. 1.

   Define voltage gain.

   Hint

   Think about what happens to your input signal after amplification.

2. 2.

   What does output swing refer to?

   Hint

   Consider the limits of the output signal indicating its maximum and minimum limits.

3. 3.

   What is the maximum achievable voltage swing with a 12 V supply?

   • ±12 V
   • ±4 V
   • ±6 V

   Hint

   Think about supply limits and output tolerances.

4. 4.

   True or False: The voltage gain can be arbitrarily increased by changing circuit parameters.

   • True
   • False

   Hint

   Consider the physical limits of the devices being used.

5. 5.

   Design a common gate amplifier circuit that requires an output swing of ±6 V using a 12 V supply. Use appropriate calculations to find the resistor values that meet this requirement as well as an input impedance of 200 Ω.

   Hint

   Focus on the voltage division principles and Ohm’s law when designing your circuit.

6. 6.

   Explain why a voltage gain of 100 might not be achievable in a common gate amplifier. Discuss the reasons concerning device limits and circuit parameters.

   Hint

   Consider the specifications outlined in the device parameters.
