A complete GaAs HEMT single chip data receiver for 40 Gbit/s data rates

Using our 0.2 /spl mu/m AlGaAs-GaAs-AlGaAs quantum well HEMT technology, we have designed, manufactured and characterized a single chip comprising a clock recovery, a data decision and a 2:4 demultiplexer circuit. The chip is able to receive a data stream of 40 Gbit/s and converts it into a four bit parallel data signal. The results presented here have been measured on wafer.
