69.1. Analog Electronic Circuits

Try these first

1. 1.

   Explain the difference between active and passive loads.

   Hint

   Remember the role of each in an amplifier.

2. 2.

   What is early voltage?

   Hint

   Consider its role in transistor characteristics.

3. 3.

   What is an active load?

   • A resistor
   • A transistor
   • A capacitor

   Hint

   Think about the components that can enhance gain.

4. 4.

   True or False: Early voltage has no impact on amplifier stability.

   • True
   • False

   Hint

   Recall the role of early voltage in transistor operation.

5. 5.

   Design a CE amplifier circuit that can tolerate a 15% drop in beta without significantly affecting output stability.

   Hint

   Balance feedback against design parameters.

6. 6.

   Discuss the trade-offs between gain and stability in a CE amplifier design using both active and passive loads.

   Hint

   Consider the implications for gain vs. operational ranges.
