43.3.1. General Expectations from Cascading

Try these first

1. 1.

   What is the main advantage of cascading amplifiers?

   Hint

   Think about why we would connect multiple amplifiers.

2. 2.

   Define the term 'loading effect' in your own words.

   Hint

   Consider how components affect each other when connected.

3. 3.

   What is the expected total gain when two amplifiers with gains of 10 are cascaded?

   • 10
   • 100
   • 5

   Hint

   Remember how cascading amplifiers works.

4. 4.

   True or False: Cascading amplifiers always results in increased overall gain.

   • True
   • False

   Hint

   Consider the loading effects.

5. 5.

   You are tasked to design a two-stage amplifier using CE configurations. Given the resistances and expected bandwidth, predict the gain and bandwidth. Consider how loading might impact these values.

   Hint

   Examine resistances and their parallel effects.

6. 6.

   Create a cascading design for two CS amplifiers, including a buffer. How does the requirement for high input resistance and low capacitance in buffers influence your design choices?

   Hint

   Consider various buffer configurations available.
