66.6.2. I-V Characteristic Curve

Try these first

1. 1.

   What is an active load in an amplifier?

   Hint

   Think about what replaces resistors in an amplifier.

2. 2.

   What does the I-V characteristic curve illustrate?

   Hint

   Consider what happens to current as voltage changes.

3. 3.

   What is the primary advantage of using an active load in amplifiers?

   • Lower power consumption
   • Higher voltage gain
   • Increased noise
   • Simplicity

   Hint

   Think about how amplification is affected.

4. 4.

   In which region does the collector current remain steady for a common emitter amplifier?

   • True
   • False

   Hint

   Reflect on the behavior of the transistor during operation.

5. 5.

   Design a common emitter amplifier that maximizes voltage gain while keeping the power dissipation within acceptable limits. What are the key parameters you'd adjust?

   Hint

   Reflect on gain limitations and how to optimize design parameters in practice.

6. 6.

   Explain the trade-offs when moving from passive to active loads in terms of cost, complexity, and performance in a circuit.

   Hint

   Consider the overall system design and what’s prioritized in application.
