41.2.5. Transfer Function Derivation

Try these first

1. 1.

   What does the capacitor contribute to the frequency response in amplifiers?

   Hint

   Think about how capacitors behave at different frequencies.

2. 2.

   Define 'pole' in the context of a transfer function.

   Hint

   Where does the function spike?

3. 3.

   What is the purpose of the transfer function?

   • To understand input-output relationships
   • To measure direct current
   • To reduce noise

   Hint

   Think about analysis in circuit design.

4. 4.

   True or False: A zero in a transfer function indicates a frequency where the output is maximized.

   • True
   • False

   Hint

   Consider the role of numerator over denominator.

5. 5.

   Design a CE amplifier that can effectively respond at high frequencies, considering the selected components lead to a gain of 100 and placing poles correctly.

   Hint

   Use the transfer function to calculate the effect of each component.

6. 6.

   Analyze how varying C affects the pole locations in your previous circuit design. What trends do you expect?

   Hint

   Observe how pole locations shift as you operate the circuit.
