phase frequency detector

hello
i want to design pfd, i intend to use the conventional pfd, so i need to design fully differential CML d-flip flop with reset and similar and/nand gate, so if any one has resources like papers, books,links , discussing this issue or discussing the cmos cml logic in general ,please upload it ,note: i work on 0.18u cmos technology, and at approximately 1GHz frequency
thanks

Re: phase frequency detector

ok, what in the jssc that i saw is discussing mainly new methodologies for the pfd , and express the gates with its symbol,and the schematics i saw doesnt contain the d-ff i wanted asa i want it resetable fullydifferential, so as you said there is a lot you might seen it, so can you please upload one of them if they contain the resetable d-ff?,,,,,anyway my question mainly target the implementation of resettable d-ff cml and similar "AND" gate
thanks for replying

Re: phase frequency detector

I believe the working frequency of your PFD is not 1GHz. If it's less than a couple of hundred MHz, then normal DFFs should be enough. For differential CML DFF, you can refer to Mike Perrott's lecture notes about high-speed IC. (MIT )

you can find some papers about CML :
1、A GHz MOS Adaptive Pipeline Technique Using
MOS Current-Mode Logic,IEEE JOURNAL OF SOLID-STATE CIRCUITS, VOL. 31 NO. 6, JUNE 1996
2、2-GHz/2-mW and 12-GHz/30-mW Dual-Modulus Prescalers in Silicon Bipolar Technology,IEEE JOURNAL OF SOLID-STATE CIRCUITS, VOL. 36, NO. 9, SEPTEMBER 2001
