    Capacitor Mismatch Coefficient for gpdk 180nm technology Reply

     Hi experts,

    I am designing a 8 bit CDAC for the SAR ADC that I want to design for my masters project. Regarding this, I want to know about mismatch coefficient of capacitors (Ac) for gpdk 180 nm tech. because, using the mismatch concept I can decide on the LSB cap value that I need to use.

    Anyone having any information regarding this, please help me out....

    Regards,
    Indrajit

    Hi Indrajit,

    Er, it's not a real technology, so it's a bit hard to characterize what the mismatch between devices would be!

    The whole point of gpdk180 is that it is a sample, vaguely representative, 0.18um technology. You can pick whatever number you like! (I'm not sure what you mean by "mismatch coefficient" anyway, but it's not something that is included in the PDK). There are some basic monte carlo models which should include some mismatch variation - but how realistic they are is debatable (it's a moot point anyway, since the whole process is fictional).

    Regards,

    Andrew.
