Summary: 
This letter reports a high-sensitivity GaAs decision IC for ultra-high-speed optical transmission systems. The IC was designed using LSCFL (Low-power Source Coupled FET Logic) and fabricated with 0.2-µm-gate-length MESFETs with a cut-off frequency of 50GHz. The input voltage sensitivity was 35mV at 10Gbit/s. This is the highest sensitivity ever reported for a MESFET decision IC.
