DC simulation with spiral inductor

    Hi all,

    I am confused when I simulate a simple common drain circuit with spiral
    inductor connected to the source of nmos and then ground. I perform dc
    simulation and it shows me that it can't converged. When I remove the spiral
    inductor, it works fine...

    Why???

    Cheers,
    Fred

    Not enough information, sorry...

    This will depend a lot on the spiral inductor model, which simulator you're
    using, how long a piece of string is, and so on...

    Andrew.
