    Hi to all,

    Actually I design an Operational Transconductance Amplifier OTA,
    I do the different type of simulation but the noise simulation doesn't
    work when I simulate the OTA with an AC source and a noise simulation
    (I obtained the same value of noise in every node in the circuit).
    Can any person tell me how to do this type of simulation and what is
    the applicated source?


    Thanks to all.

    Really? What simulator are you using, and how are you setting it up?

    For spectre you don't need an AC source - you only need to tell the
    noise analysis where the output of the circuit is - i.e. where to
    measure the noise.

    Regards,

    Andrew.

    You need to do more than choose the output. You must also tell ADE
    where the source is -- voltage, current, or probe.
