Abstract :
A modulator driver has been developed for use in 40 Gbit/s optical transmission systems. It is a two-stage device with distributed amplifiers in the stages. Which is monolithically integrated on a single chip with a high gain of 20 dB. High output voltage swing of 5 V and ultraboadband operation with a bandwidth of 46 GHz
