An ultra low power AlGaAs/InGaAs HJFET SCFL circuit for 10 Gbps applications with 1.3 V supply voltage

SCFL D-FFs with supply voltage as low as 1.3 V are designed and fabricated. The supply voltage is decreased by optimizing the logic swing and the voltage shift in the source followers. The D-FFs, using 0.25 /spl mu/m AlGaAs/InGaAs HJFETs, operate at up to 10 Gbps, with power consumption as low as 19 mW.
