    Hi All,

    I encountered something frustrated. I am using both Unix Cadece 4.46 and
    Cadence 5.032. Even for the same design kit, I found that the results given
    by them
    are different! I found that there are about 1~2 dB difference in
    S-parameters simulation.
    Also, the curve shift! Have anyone experienced the same problem?

    We did see different noise results between 446 and 50. It turned out
    to be the addition of the wdexp and ldexp resistor parameters. When
    we set them to 1 we get the same results in 50 as 446.
