A super-dynamic flip-flop circuit for broadband applications up to 24 Gbit/s utilizing production-level 0.2-/spl mu/m GaAs MESFETs

摘要

This paper describes a novel dynamic flip-flop (FF) circuit that can operate 30% faster than conventional clocked inverter-type FFs. A new wide-band clock buffer is introduced to cover the FF operation range. An 8- to 24-Gbit/s decision circuit and a 9- to 26-GHz 1/2 frequency divider were developed using production-level 0.2-/spl mu/m GaAs MESFET technology.
