66.6.1. Voltage Gain Limitations

Try these first

1. 1.

   What does voltage gain represent in an amplifier?

   Hint

   Think about how much the amplifier changes the input voltage.

2. 2.

   What is a common emitter amplifier?

   Hint

   It uses a specific type of transistor.

3. 3.

   What defines the voltage gain in an amplifier?

   • Output power to input power
   • Output voltage to input voltage
   • Output current to input current

   Hint

   Focus on the voltage aspects of the gain.

4. 4.

   Is it true that an active load can increase the voltage gain of an amplifier?

   • True
   • False

   Hint

   Think about how active components function in circuits.

5. 5.

   Design a common emitter amplifier using an active load that achieves a voltage gain of at least 10, given a quiescent collector current of 3mA and a supply voltage of 10V. What considerations should you keep in mind?

   Hint

   Focus on balancing gain with voltage constraints.

6. 6.

   Discuss the trade-offs in using higher resistance in passive loads versus implementing an active load in terms of gain and thermal management.

   Hint

   Analyze the benefits of thermal management in designs.
