四題任選兩題

1. Make the Bode plot of Circuit in Example 1, as below. You must verify the results for correctness.

The results must be scientifically accurate.

Topology B in Schematic

Reference materials:

You may want to generate Python for the Bode plots. Then you  carry it out to the end.

How to make Bode plots 

Make Bode plot:

• Use of Gemini 3.0 Pro slides (Example 1, CE)
• Use of Claude Sonnet 4.6 slides (Example 1, CE)
• 
  

ChatGPT can generate Python like Claude/Gemini, Therefore, you can study  

• Use of Gemini 3.0 Pro slides (Example 1, CE)

Key takeaways:

 

Put your Python to run on Google's colab platform. 

Plots can be made more professional and well suited for formal documents such as reports or academic journals.

You may want to label it more clearly following IEEE standard.

• Artifact, Share (Cπ2=15 pF, Cμ2=3pF). Result: freq response, gain=8513, low cut off=46.5 Hz, high cut off=312kHz
• Gemini: Result gain=8509, low cut off=46.5 Hz, high cut off=296 kHz @Cπ2=15 pF, Cμ2=3pF (good match!)
