adaptive CMOS buffers for clock trees

[meeyaw]

Hi all,

Is anyone here started/already designing clock trees/mesh using adaptive CMOS buffers? Then, what are the things to consider in doing those things.

I've asked this as I was trying to do a self-research on CMOS buffer implementations.

Thank you very much for the answers.

To clarify the query above, when I say adaptive, it means that the design is stable across PVT, or its slew rate is adjustable to the number of loads it drives or the drive current - some sort of like that.

I have asked this because I want to see other ways of designing clock buffers for distribution trees aside from conventional CMOS inverters and integrating DLLs for skew adjustment. Thanks for any insights you may give.
