A 72 Gb/s 2/sup 31/-1 PRBS generator in SiGe BiCMOS technology

A 2/sup 31/-1 72 Gb/s PRBS generator is reported in a 0.13 /spl mu/m SiGe BiCMOS technology with 150 GHz-f/sub T/ HBTs. Variable delays are introduced along the 36 GHz clock path to increase timing margins. A true BiCMOS logic family using NMOS FETs in the clock path is employed throughout the circuit, which dissipates 9.28 W from a 3.3 V supply to provide a single-ended output swing of 300 mV at 72 Gb/s.
