Abstract :
A D-flip flop IC and a 2:1 selector IC using DCFL have been developed for applications operating above 10 Gb/s. Memory cell type flip flop (MCFF) is used for the D-flip flop IC. These ICs are fabricated using 0.2 mu m gate pseudomorphic inverted HEMTs (high electron mobility transistors), which show a high transconductance of 580 mS/mm, a high cutoff frequency of 110 GHz, and a low drain conductance of 17 mS/mm. The operations of the D-flip flop and the 2:1 selector ICs are confirmed up to 20 Gb/s by a measurement system composed of these ICs. The power dissipation is 430 mW for the D-flip flop IC and 170 mW for the 2:1 selector IC.<>
