    How to measure linearity of an input buffer in Cadence

    Dear all,

    I am now designing an input buffer in the track and hold (using switched emitter topology). I was wondering how should I test the input buffer that I have designed in Cadence? What kind of measurement should I be taking? P1dB? IIP3? Can anyone please provide me guildance on how to carry out those measurement in Cadence. Thank you very much for your time! :D[/b]

    How to measure linearity of an input buffer in Cadence

    you can do the IIP3 analysis and then convert the input power to voltage
