A high-speed and high-gain modulator driver circuit is presented using 4-inch InP SHBT technology. The IC was developed for driving EAM modulators in 40 Gbit/s optical fibre systems. The monolithic integrated circuit features output amplitude control and output crossing point control. Measured results show the circuit operates at 40 Gbit/s with a swing of 2.5 Vp-p at each output and 9/8 ps rise/fall times. The power dissipation is 1.5 W with a standard power supply of −5.2 V.
