Reference needed for Flip-flop working above 10GHz

[KGxiaoyun]

I am working on phase detector and flip flop is one essential part of it. However, I cannot find many useful reference on flip flops that could work beyond 10+GHz. Right now I only find one of Razavi's paper on 40Gb/s CDR circuit, but I don't quite understand it.
So can anyone recommend any reference to me on that,please?
Or any reference on flip flop bascis is fine. Thanks

Why not try a CML based logic circuits (If power is not a concern). I don't have a reference paper at this moment but you can google it. Lots of materials are available.
Again you have to select proper technology node having high ft numbers for MOSFETs (for operation >10GHz typically ft of >50-60GHz should work). Lower the technology (60nm, 40nm or 28nm may be) higher is the frequency of operation.

Hope this will help ..

Thanks! I am using 65nm technology
