    Colin, I would leave it separate from the Agilent site and be clear about your current affiliation. […] You also have 6 months of inbound links that you might forfeit in the move.

    I like your podcast.

    Hello Mr . Warwick,
    my name is Kavan and I am a student. I found your white paper “Understanding the Kramers-Kronig
    Relation Using A Pictorial Proof”.
    Very good.
    I would like to ask you a few clarifying questions if possible. I am just a beginner.
    Let me know if it is feasible,

    sir are u or your organisation giving training on ADS to design a power amplifier on GaNbased ? kindly tell me some suggestion to take training to design the power amplifier by using ADS any help i will be highly obliged I M FROM INDIA

  • jagatpati raiguru

    please reply me sirColin Warwick so that i will be benifited : sir my introduction is i m a student of microelectronics 2012 2014 i want to desiogn apoweramplifier on GAN BASED please give me some tips and if possible please tell me the training schudle training cost i woulb be highly o0bliged sir thanku sir

    hi Mr.Warwick
    please help me
    i want to simulation a mems capacitor in ADS and analyses this variable capacitor
    this variable capacitor simulated in intellisuite and And a change in the relationship between pressure and capacitance using MATLAB earned.
    I want this variable capacitor as a microphone connected to the an amplifier .
    But I do not know how to use the intermediate circuit.

    Thank you so much for your help

    Hi Javad,

    I don’t know but if you open a tech support ticket, I’m sure we can figure it out. ADS has a feature called Symbolically Defined Devices that allows you to create a device based on your own branch constitutive equations. Search the doc for “SDD”

    Best regards,

    Hi Sir, all your submissions on KKT have been particularly interesting, and I want to thank you for that. Sir may I humbly request for a sample MATLAB code that would help me obtain the real part of susceptibility. I’ve computed the imaginary part with my theory. I’ll be glad if you respond to this. Thanks so much

  • Colin Warwick

    Hi Chijioke, Sorry I don’t know how to help you with that request.
