Try these first

1. 1.

   What is the role of capacitance in amplifier circuits?

   Hint

   Think about how capacitors act in AC circuits.

2. 2.

   What does Miller's theorem help us accomplish in circuit analysis?

   Hint

   Recall the concept of two equivalent parts in a circuit.

3. 3.

   What is the primary purpose of analyzing frequency response in amplifiers?

   • To determine voltage gain
   • To check stability
   • To analyze behavior at different frequencies

   Hint

   Think about the variations in signals.

4. 4.

   True or False: Miller's theorem splits capacitances into two parts for easier analysis.

   • True
   • False

   Hint

   Look back at what we covered about circuit simplification.

5. 5.

   Given a common source amplifier with specified values for capacitances and gains, derive the input and output capacitance using Miller's theorem and analyze the effect on frequency response.

   Hint

   Recall the methods to apply Miller's theorem to each capacitance.

6. 6.

   Design a theoretical experiment using both CE and CS amplifiers to measure the differences in high-frequency response, and detail your findings.

   Hint

   Focus on measuring the frequency response at both high and low limits.
