35.2. Frequency Response of CE and CS Amplifiers (Part A)

Try these first

1. 1.

   Define frequency response.

   Hint

   Think about how output varies with different frequencies.

2. 2.

   What is a cutoff frequency?

   Hint

   What point signifies a significant change in output?

3. 3.

   What does frequency response measure?

   • Output variation with temperature
   • Output variation with input frequency
   • Input voltage levels

   Hint

   Focus on how output relates to changing input conditions.

4. 4.

   True or False: The cutoff frequency is where an amplifier's gain begins to drop significantly.

   • True
   • False

   Hint

   Consider what significance this point entails for amplifiers.

5. 5.

   Given an RC circuit with R = 10kΩ and C = 100nF, derive and plot the frequency response. Identify key frequency points.

   Hint

   Calculate using the standard transfer function form and substitute R and C values.

6. 6.

   In a common emitter amplifier, if the feedback capacitor is increased, how would it affect the frequency response? Analyze the potential impact.

   Hint

   Consider how the behavior of capacitors affect frequency response.
