A 12-channel, 2.5 Gb/s, receiver IC for parallel optical interconnect is described. Each channel contains a Metal-Semiconductor-Metal Photodetector (MSM PD), Transimpedance Amplifier (TIA), Limiting Amplifier (LA), Output Buffer (OB) and Loss of Signal Detector (LOS). The chip was designed and fabricated in a 0.4 /spl mu/m GaAs MESFET process. Using a 3.3 V… (More)
