What do we see when looking at the transistor from the emitter side? AI
This is an enhanced version of my original answer to question How to analyze common-emitter amplifier by reflecting base impedance to emitter? on Stack Exchange EE generated with the assistance of Gemini AI . It is made in the form of a dialogue between me (CF) and Gemini (in italics) as I have described it in Talking with Gemini and How do we collaborate with AI in answering SE EE questions? In short, this is a story about the controversial "re" resistance seen from the emitter side of the transistor in a common-emitter and common-base stage. Legend: My lines are written in regular font and start with the caption " Circuit fantasist " in bold. Gemini's lines are in italics and start with the caption " Gemini " in italics and bold. My answer from StackExchange is in regular font. -------------------- Bad news Gemini, it is Circuit Fantasist here. I am afraid I have got some disheartening news to share.
