The results indicate that, for the present devices, gate lag is mainly caused by substrate-trap-induced threshold-voltage shift. Since these traps are required to ensure the substrate is semi-insulating, effective channel/substrate isolation is crucial for minimizing gate lag of these devices. The same technique can be used to assess the relative importance of surface vs. substrate traps to other types of devices and to help optimize their structures.","PeriodicalId":299287,"journal":{"name":"GaAs IC Symposium.

To decrease power consumption and to maximize phase margin, the clock-generating circuit employs source-coupled FET logic (SCFL) circuits. Also, cascade-connected source-follower circuits are used in the clock buffer. These circuits can reduce the power consumption when the fan-out number is large. Direct coupled FET logic (DCFL) circuits are employed for the 2:1 MUX/1:2 DEMUX circuits operating below 5 Gbps. The ICs, which are mounted on ceramic packages, operate at up to 10 Gbps with a power consumption of 1.2 W for the MUX and 1.0 W for the DEMUX at ECL-compatible supply voltages.
