    upper limit of the gain of a darlington pair

    Re: darlington pair Darlington configuration is used to increase the input impedance of a single transistor. Why to care about its current gain?

    Milller theorem fails

    Miller's theorem and virtual ground

    There are many misinterpretations of such a simple theorem, including textbooks by Razavi, Sedra, this forum, etc. For example, Razavi writes that Miller's theorem can give wrong gain. Sedra does not suggest finding the output impedance after applying Miller's theorem. A number of people on...

    Will a noise-free oscillator produce sustained oscillations?

    A generalized impedance converter

    :))) --- Not sure you are 100% right, though.

    Can electrons at absolute zero temperature move?

    Do you think, halls, that thermal energy can be associated with deterministic motion?

    Will a noise-free oscillator produce sustained oscillations?

    Re: Will a noise-free oscillator produce sustained oscillati So, this means that a zero-input response of a linear circuit cannot be a sinusoidal waveform with a constant amplitude. Is this what you say?

    Another tough 'elementary' question from my tutor

    Just a few examples: "Selective quoting..." "If you keep adjusting the conditions around your assertions then you can be always right, of course. " "Your intuitive view posits infinite speed charging, oscilatory behavior, w/o an inductance (that is, electric *and* magnetic field) , etc. Your...

    Another tough 'elementary' question from my tutor

    Thank you, n1cm0c, very much for your speculations on my personality! Studying psychology? :) Jasmine

    Another tough 'elementary' question from my tutor

    The question was: what it would be if energy loss = 0.

    Exam help! A loop-gain greater than one

    That is OK Jonathan, but what is your opinion? Do you have an explanation? Do you accept my explanation? Jasmine

    Another tough 'elementary' question from my tutor

    I have started another thread on an absolutely different problem: here we are talking about oscillators and there on electrons at 0K. BTW, you might notice that my opinion seconds yours: "Conduction band electrons are like a plasma, and will move anywhere an externally imposed field pushes...
