65.1. Analog Electronic Circuits

Try these first

1. 1.

   What does a Cascode Amplifier do?

   Hint

   Think of multiple stages in an amplifier.

2. 2.

   What is an active load?

   Hint

   Remember, it’s about using a different power source.

3. 3.

   What is the key advantage of a Cascode Amplifier?

   • Higher Cost
   • Higher Voltage Gain
   • Lower Efficiency

   Hint

   Consider the benefits of increasing gain.

4. 4.

   Is an active load better than a passive load in amplifiers?

   • True
   • False

   Hint

   Think about how gains differ.

5. 5.

   Design a Cascode Amplifier circuit using specific transistors targeting a gain of 1500. Discuss which parameters you'll modify and why.

   Hint

   Consider the active load's resistance while ensuring it can support your desired current.

6. 6.

   Analyze how the input capacitance changes with different active load resistances in a Cascode Amplifier setup. Provide numerical examples.

   Hint

   Use values from previous examples, altering R for demonstration.
