A high-speed time-division 2:1 multiplexer is presented. The IC is fabricated with the authors' standard 0.2 mu m gate-length enhancement and depletion AlGaAs/GaAs HEMT technology (integral of Tau = 60 and 55GHz). The circuit can operate up to 45Gbit/s using single-ended data and clock inputs. The differential output voltage is 1 V(p-p). The power consumption is 500 mW using a single supply voltage of -4.5 V.
