20 GHz 8b multiplexer implemented with 0.5 /spl mu/m WNx/W-gate GaAs MESFETs

High-speed multiplexers (MUXs) are key components in optical-fiber communication systems. MUXs with a higher operating frequency are desirable to realize increases in data transmission capacity. Furthermore, MUXs with a higher number of bits are also desirable to reduce the number of high-speed syst...

More Information
Summary:High-speed multiplexers (MUXs) are key components in optical-fiber communication systems. MUXs with a higher operating frequency are desirable to realize increases in data transmission capacity. Furthermore, MUXs with a higher number of bits are also desirable to reduce the number of high-speed system components. This 20 GHz 8b MUX is based on source-coupled FET logic (SCFL) and fabricated using a 0.5 /spl mu/m GaAs MESFET process based on conventional optical lithography and ion implantation. This is the fastest reported 8b MUX.< >
