How to measure the Noise Figure of a differential LNA?

    Dear all,

    Could anyone tell me how to get Noise Figure from Cadence Spectre
    simulation? I know how to do it for a single-ended LNA, but I am
    working on a differential one. If possible, please glso give me some
    hints for reducing the NF. Thanks.

    Best,
    Allen

    Use the balun from rfLib. This does an ideal single to differential (or vice
    versa) conversion. Of course, you need to put a port at the input and output as
    before, and do the noise analysis.

    Regards,

    Andrew.
