High-Speed Transmitters in 90nm CMOS for High-Density Optical Interconnects Conference Paper uri icon


  • Small, high-speed and low power optical transmitter circuits are needed for optical interconnects to play a role in improving chip I/O bandwidth. This paper demonstrates two different transmitter designs fabricated in a IV 90nm CMOS technology, one suitable for driving vertical cavity surface emitting lasers (VCSELs) and the other for driving multiple quantum well modulators (MQWMs). A four-tap current summing FIR equalizer extends VCSEL data rate for a given average current. It consumes 80mW at 18Gb/s operation and occupies 0.03mm 2 area. The MQWM transmitter has a pulsedcascode output stage capable of supplying a voltage swing of twice the IV supply without overstressing thin-oxide core devices. It consumes 38mW at 16Gb/s and occupies 0.014mm 2 area. 2006 IEEE.
