phase error in OTA amplifier

mozdas
Hi, I am designing an OTA amplifier how can I find its phase error and do thd analysis in cadence. And how can I change the phase error. Thanks in advance

  • Hi mozdas

    You can use "thd", "value" and "phase" functions from viva calculator to do the calculations. E.g.

    value(phase(VF("/OUT")) 11M) - value_of_designed_phase

    Calculator can be accessed from ADE-L at "Tools->Calculator". Hope that this is what you need.

    Best regards
    Quek
