A novel high-speed low-power tri-state driver flip flop (TD-FF) for ultra-low supply voltage GaAs heterojunction FET LSIs

Abstract

The authors describe a new GaAs static flip flop, called TD-FF (tri-state driver flip flop), for ultra-low supply voltage GaAs heterojunction FET LSIs. The TD-FF operates at a data rate of 10 Gbps with 18 mW power consumption at 0.8 V supply voltage. The 10 Gbps power consumption is 1/5 of the minimum value reported for D-FFs so far. The authors also demonstrate a 1/8 static frequency divider IC using the TD-FF configuration. This IC operates up to 10 GHz with 38 mW at 0.8 V supply voltage.<>
