6.8 mW 2.5 Gb/s and 42.5 mW 5 Gb/s 1:8 CMOS demultiplexers

This paper presents two low-power demultiplexers working at 2.5 Gbps and 5 Gbps input data rate respectively. The 2.5 Gbps demultiplexer consumes only 6.8 mW power dissipation. The 5 Gbps demultiplexer consumes 42.5 mW power dissipation. The two demultiplexers are implemented in TSMC 0.35 /spl mu/m CMOS technology. They are built on the same chip sharing input and output ports. The power supply of the chip is 2.5 V. The demultiplexers are designed to be modules for optical communication receiver systems.
