69.3.3. Comparison with Passive Load

Try these first

1. 1.

   What is a passive load?

   Hint

   Think about components that don’t amplify signals.

2. 2.

   Define transistor beta (β).

   Hint

   What does it say about the relationship of the currents?

3. 3.

   What is a characteristic of an active load?

   • Enhances gain
   • Only passive components
   • Lower complexity

   Hint

   Consider what distinguishes active loads from passive ones.

4. 4.

   True or False: Early voltage changes have no effect on amplifier output.

   • True
   • False

   Hint

   Think about the implications of early voltage on operational parameters.

5. 5.

   Design a CE amplifier with active load. Given that the early voltage is increased, how would you adjust the biasing resistors to maintain output stability?

   Hint

   Consider how early voltage adjustments influence output stability and bias points.

6. 6.

   Given a circuit with a passive load, what potential issues arise when the transistor beta decreases? Discuss a solution.

   Hint

   Think about feedback's role in stabilizing varying parameters.
