Abstract:
A 10 Gbit/s 1∶4 demultiplexer(DEMUX)fabricated in 0.18 μm CMOS(complementary metal-oxide-semiconductor transistor)technology for optical-fiber-link is presented.The system is constructed in tree-type structure and it includes a high-speed 1〓 ∶2 DEMUX, two low-speed 1〓 ∶2 DEMUXs, a divider, and input and output buffers for data and clock.To improve the circuit performance and reduce the power consumption, a latch structure with a common-gate topology and a single clock phase is employed in the high-speed 1∶2 DEMUX and the 5 GHz 1∶2 on-chip frequency divider, while dynamic CMOS logic is adopted in the low-speed 1∶2 DEMUXs.Measured results at 10 Gbit/s by 231-1 pseudo random bit sequences(PRBS)via on-wafer testing indicate that it can work well with a power dissipation of less than 100 mW at 1.8 V supply voltage.The die area of the DEMUX is 0.65 mm×0.75 mm.
