65.2.1. Common Source Amplifier Benefits

Try these first

1. 1.

   What does the common source amplifier primarily amplify?

   Hint

   Consider the type of input this amplifier typically processes.

2. 2.

   Name an advantage of using an active load instead of a passive load.

   Hint

   Think about how components can contribute to gain.

3. 3.

   What is the primary advantage of using an active load in amplifiers?

   • Increased voltage
   • Higher gain
   • Reduced cost

   Hint

   Focus on what active loads do differently from passive ones.

4. 4.

   True or False: Increasing the gain of an amplifier will always improve its bandwidth.

   • True
   • False

   Hint

   What do you recall about the relationship between gain and bandwidth?

5. 5.

   Evaluate the implications of using a common source amplifier with a gain of 5000 and how this impacts design choices for bandwidth.

   Hint

   Think about your gain-bandwidth product knowledge.

6. 6.

   Design an example problem where you transition from passive to active load and calculate expected differences in gain and bandwidth.

   Hint

   Use calculations and relationships previously discussed.
