    design digital circuits at serveral GHz

    Of course one option is to be aggressive on process such as using 65nm. However any new idea can be used on that such as custom cells ...........

    Re: design digital circuits at serveral GHz

    Different high speed logic families can work at the GHz range. For example, current mode logic (CML) and dynamic logic. Actually, these two families are used for frequency dividers for PLLs working at multi-GHz frequency.

    design digital circuits at serveral GHz

    Hi

    I thinks the the delay of an inverter in every process is the corner case. We can design a ring oscillator with only three inverter.
