Abstract:The transceiver integrated circuits tehcnology of 2.5-40Gb/s was studied for optical-fiber communication. The ICs include multiplexer, laser-driver, preamplifier and limiting amplifier, clock recovery and data decision, demultiplexer. The technologies of 0.18/0.25μm CMOS, 0.15/0.2μm GaAs PHEMT and 2μm GaAs HBT were used to research and design the ICs. The MPW(multi-projet wafer) method and advanced foundry technology were adopted to produce the ICs. The high-speed circuit technology and MMIC technology were adopted to research our circuit, such as SCFL structure, super-dynamic DFF, synchronization injection VCO, distributed amplifier, coplanar waveguide and transmission-line technology. The 155Mb/s-2.5Gb/s SDH transceiver ICs was produced. The developing trand of above 40Gb/s ICs design technology was discussed, including high-speed device modeling and the ICs testing.
