@Tony, thanks for the interesting observations. I am glad to see that you are not only a great circuit designer but also a "circuit philosopher". I will try to add some of my views to your philosophy...
▪︎ In my opinion, "eliminate the Vbe diode voltage offset from the input" is because the trans... (more) |

@Tony, I think when there is a resistor connected between the emitter and the supply rail, that's another story named *negative feedback* ("emitter degeneration")... (more) |

@Tony, What is the common terminal in the circuit of a common-emitter stage with emitter degeneration? It should be a point with fixed voltage... but there is no such point. All the transistor terminal voltages are varying... (more) |

@Tony, the very title of this story specifies that it is about the idea - the structure, the topology of the circuit solution. Inventing the circuit and calculating it are different things - the former is something qualitative; the second is quantitative. It is incorrect to explain qualitative things... (more) |

What is the idea behind the transistor differential amplifier? It was a big challenge for me to show the basic idea behind the op-amp instrumentation amplifier by building and reinventing it step by step. But it is no less challenging to show the idea behind the simpler but legendary transistor differential amplifier (figuratively named "long-tailed pair"). I wi... (more) |
