    gm/id for switch cap circuits design (CMOS in triode)

    Hi everyone,
    Is there any way to use gm/id design methodology for switched cap circuits design ? I mean could it be used to design a CMOS switch (in triode region) ? if so then what are the required curves to be generated ? if not then is there any other similar technique that can be used ?
    you know, hand calculations in submicron technologies are not useful at all !

    gm/Id is mostly for DC operating points and small-signal parameters. Switched-capacitor circuits will require a transient simulation. You may get a good starting point with gm/Id, but you'll have to do simulation-based sizing (tweak-simulate-tweak) anyway, maybe with an optimizer software, and could start with it right away.
