    Gut into a discussion the other day about the use of
    bipolar transistors.

    I told them I was
    negatively biased on PNPs

  2. Rub some Saint John's Wort on them.

    Many thanks,

    And many are also bipolar, so they can have mood swings.

    But that's all OT here anyhow because it's got nothing to do with global
    warming :)

    Unless you're over biased!
  5. What global warming? Decembers first snow is right on time!

    Even Houston had snow. That really doesn't happen often.

    What's your current opinion on that?

  8. I think this is all a bit emotionally charged.

    Only for people working outside their field.

  10. Hm, perhaps it's my shielded upbringing, but I fail to see the connection.
    Or are we talking about isolated cases here?

    SemiConductor Theory
    (c) 1997 by Gareth Alun Evans

    A transistor is rather like the human alimentary canal, after the
    typical USA diet of burgers and chips; - it constipates, as do
    semiconductor diodes with no applied bias - the available holes get
    filled in and nothing can move.
    The base current is like a small application of laxative; some of
    the constipation passes through, until the effect of the laxative wears
    off. The total throughput depends upon the Mobility. By applying a
    continuous feed of laxative, then a continuous current passes through.
    Applying too much laxative results in saturation - ie, there is a limit
    to the maximum throughput, depending on the external circuit; in this
    case, the maximum rate at which you can feed in the burgers at one end.
    (If you are a customer of MacDonalds's, here in Chippenham, Wiltshire,
    UK then this rate is very low - I have been there twice, and both times,
    the service was *APPALLING*.)
    The difference between PNP and NPN is the direction. In the old
    days, PNP was used, whereby one injected from the rear end, using a sort
    of huge syringe - hence PNP - "Put-in Near Poo". More recently NPN is
    more common, where the laxative is entered via a carrier of some sort,
    usually chocolate and so we have NPN - "Now Pleasant Nutrient".
    Despite the adverse effects, the USA diet of burgers and chips
    carries on, and recourse has to be made once again to the chocolate. Now
    the ratio of the carriers of the constipation, the burgers and chips, is
    much higher than that of the chocolate. Thus they are referred to as the
    Majority Carriers and the Minority Carriers. If you indulge too much,
    you find that the vendor will provide you with a paper bag, known as an
    Excess Carrier.
    More recently, there are problems with impurities and you find that
    the opposite effect occurs. You have no time to reach home before
    diarrhoea takes over. You have no option but to stop the car and nip
    over a gate into a field. Hence the Field Effect Transistor. This time
    you have to inject something to STOP the flow. Now, assuming that there
    was a certain control over events; nothing happened until the Gate was
    encountered, you then became the Source of flow, and the field itself
    acted as the Drain. What was originally dirt, became grass, was consumed
    by the Cow, you ate it as a burger, and it has now returned to the
    topsoil, an effect known in the trade as Surface Recombination.
    (Incidentally, did you know that Diarrhoea is hereditary? Apparently it
    runs in the jeans.)
    Some of the impurities accumulate in your rear end, and no matter how
    valiently you try, you cannot rid yourself of them. Hence In-de-Bum is
    known as a Try-Valient Impurity. In the same way, Arse-nic, well known
    for its ill-effects and accumulation in the body tissues is known as a
    Pent-Up-Valient Impurity.

    Kid, you're wasting your potential.

    Guys, collect yourself and watch that what you emit is based well. If
    you just let everything out of the gate without stating proper sources
    it's draining everyone here ...
  15. Admittedly, we're lacking a common ground, the signal-to-noise ratio isn't
    very good, and I much prefer solid arguments over the vapour deposition
    taking place here, but that's still no reason for your baseless
