    Transistor transient behaviour

    Hello There, Just so everybody understands your circuit, you are driving your bjt's collector right?, as in active load? There could be many reasons for this, since you say abrupt increase/decrease in supply level, I assume you are driving the bjt with a square wave sig.gen. with the d.c. level...

    Current sources, early voltage in BJT's, Ohms law violation

    current source bjt has resistances Hi dennis, I am not sure what you mean by BTW, what I mean by 'soggy' is just an ordinary passive positive gradient resistor that you buy at the shops, 'Deck' is indeed ground or 0V potential. When you refer to Ohmic models of the transistor and there are...

    Current sources, early voltage in BJT's, Ohms law violation

    early voltage 2n3904 Hello Dennis, First of all, I would like to apoligise for sounding abit stern maybe?, secondly I don't consider that you crossed my line except that you may have come across as overly confident about a problem that has puzzled me for a very long time.Thirdly, I think this...

    Current sources, early voltage in BJT's, Ohms law violation

    thevenin transistor Hi There, Thanks for your detailed reply, but I think you have missed my point entirely.Why you must use starting conditions with nth decimal places and a Vce 10V is not clear as this is going to make it difficult for others to read, nevertheless, I shall use your figures...

    Current sources, early voltage in BJT's, Ohms law violation

    early voltage of bjt Hello there, Greetings all, I am new here so I have a few nagging questions about BJT operational characterstics. According to electrical theory, a current source can be constructed and understood by taking a high voltage source and placing a resistive potential divider...
