The authors report on a 22-Gbit/s static decision IC fabricated with 0.12-m
u m GaAs MESFETs. The key to attaining high-speed decision IC is the employ
ment of a novel high-speed D-type Rip-flop (D-FF). The D-FF succeeds in Eas
ter operation through the simplification of the circuitry and the reduction
of the transition time of the output voltages.
