    high speed mos switch

    Hi all,
    I am trying to design a high speed mos switch for around 8-10gbps serial data(wired communication application). I am at present having not many ideas on how to go forward. I need some bandwidth improvement techniques which don't consume much area. I have read about t-coil inductive peaking,but I have lot many similar switches in my design,that it takes up large area.
    Please suggest few ideas on how to go forward.Any papers on the switch architectures would be really helpful.

    Re: high speed mos switch

    Begin with the basics. Do you mean switch, like an
    RF / analog switch, where you already have the
    drivers and the summing point and only want to
    steer, or do you mean switch for two digital lines
    that acts like a logic multiplexer? Fundamental
    topology choices. Is this a 100-ohm differential
    system throughout, or are you intending to also
    transform impedance at some point (like higher-Z
    on chip signals that need also to be gained up to
    drive off chip)?

    Please look at "www.hittite.com". They offer fast logic ICs, I used their fast comparators as pulse formers or switches for Gbps stream.

    It is an RF/analog switch,I am trying to design. Yes it is just a serial link for around 8-10gbps with 50ohm termination.
