High-speed GaAs MESFET digital IC design for optical communication systems

摘要

This paper describes a high-speed GaAs MESFET digital IC design for optical communication systems. We propose novel circuit configurations of a selector and a static delayed flip-flop which are key elements to perform high-speed digital functions. Employing these new design, the selector IC and static decision IC fabricated with 0.12-/spl mu/m GaAs MESFET operated up to 44 Gbit./s and 22 Gbit/s, respectively. These performances are record speed for GaAs MESFETs.
