Abstract :
Design of a 40 Gb/s VCSEL driver IC capable of providing up to 10mA current to common-cathode VCSELs is presented. Using low-power bandwidth enhancement techniques, a prototype IC is successfully developed in 180-GHz SiGe BiCMOS technology. Measured results show 34 GHz of bandwidth, open eye diagram with rise/fall time below 10 ps, and power dissipation of 130 mW.
