Summary of the Paradigm Shift

Feature	Old UI (Graphical User Interface)	New UI (Generative Interface)
Input	Clicks, Drag-and-Drop, Menus	Natural Language (Text/Voice)
Skill Required	Tool proficiency (How to use the software)	Articulation (How to describe the goal)
Output	Static results based on manual input	Dynamic, unique results generated on the fly
Friction	High (Many steps to achieve 1 result)	Low (1 step to achieve complex result)

任選兩題

1. Plot frequency response for the following amplifier circuit using matplotlib

Compare two methods Claude Sonnet 4.5 Freq resp (all in one) vs. staged

AI Model Results:

• Grok 4: Share Link (considers parasitic capacitance Cπ ≈ 50 pF, Cμ ≈ 2 pF) - Bode Plot (188 kHz)
• Claude: Bode Plot gives 188 kHz, 
• ChatGPT 5: Share Link gives 187 kHz
• Gemini 2.5 Pro: Share Link gives 188 kHz

Note: Lower cut-off comes from coupling capacitors (not shown here).

Generate professional grade Bode plot.

3. Solve for the gain. Plot frequency response for the following  amplifier circuit.

Source

share (Av=-2.31, Lower Cutoff 20 Hz, Upper Cutoff 10.46MHz)

Analysis with Cπ = 22.1 pF, Cμ = 3.0 pF

20Hz is assumed, not by calculation

Analysis with Cπ = 22.1 pF, Cμ = 3.0 pF: 

• Bode plot, fH = 10.46 MHz, RE not bypassed
