64.3.1. Large Resistance Considerations

Try these first

1. 1.

   What is a cascode amplifier?

   Hint

   Think about amplifiers that stack stages.

2. 2.

   Name one benefit of using a cascode amplifier.

   Hint

   What does it mean to enhance the signal?

3. 3.

   What is the primary advantage of using a cascode amplifier?

   • Increased power consumption
   • Higher gain
   • Easier circuit design

   Hint

   Focus on what 'cascode' aims to achieve in circuits.

4. 4.

   True or False: Large resistances generally reduce the bandwidth of an amplifier.

   • True
   • False

   Hint

   Think about the effect resistance has on frequency responses.

5. 5.

   Design a cascode amplifier with a given load of 5 MΩ and an optimal gain requirement. Discuss how to best configure your resistive components and the impact on bandwidth.

   Hint

   Consider how resistance values influence each parameter in your design.

6. 6.

   You are tasked with creating two versions of the same amplifier—one with passive biasing and the other with active biasing. Predict the performance metrics for each configuration considering large resistances.

   Hint

   Think about the stability and adaptability of each configuration in varying conditions.
