50 Gbit/s 2:1 multiplexer in 0.13 µm CMOS technology
A fully integrated 2:1 multiplexer IC which operates at up to 50 Gbit/s data rate is presented. The MUX uses inductive shunt peaking and an output series inductor for higher bandwidth. The MUX directly drives the 50 Ω load. The IC is fabricated in a 0.13 µm bulk CMOS technology and draws 65 mA at 1.5 V supply voltage. The output voltage swing is 2×100 mV.
