Abstract :
A GaAs buffering circuit LSI for ultra-fast data processing systems has been developed. The LSI with CML compatible interface and +1.5/-3.3-V power supply voltage has successfully achieved 2-ns data cycle time with 4.8-W chip power dissipation. The circuit was designed to accommodate the basic variations in FET parameters over the operating temperature range. Refractory metal gate lightly-doped drain (LDD) MESFET technology was employed. The gate length is 1.0 mu m. WSi-W bilayer metallization system was used to reduce the gate resistance.<>
