    Hi All,

    I encountered something frustrated. I am using both Unix Cadece 4.46 and
    Linux
    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?

    Ntfs:
    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.
