Abstract
In this paper, we present a 40 Gb/s VCSEL driver (4 x 10 channels, 1 Gbps/ch) designed and fabricated in HYNIX 0.35 micrometers 2-poly 4-matel CMOS technology. The CMOS driver designed for a free space optical interconnect system consists of two NMOS for driving a VCSEL and protection circuit rejecting influence of electrostatic discharge (ESD) or unexpected input signal with several tens voltage amplitude. Two NMOS with CMOS channel length of 0.4 micrometers and width of 100 micrometers are used for adjusting dc bias current from 0 to 27 mA and ac modulation current from 0 to 13.8 mA. Protection circuit is made of two diodes. The purpose of the protection circuit is to permit the input modulation voltage range only from -5 to 5 V.
