10 Gb/s single-ended laser driver in 0.35/spl mu/m SiGe BiCMOS technology

This paper presents a high-efficiency 10 Gb/s single-ended laser driver using a novel operating point control scheme. The cascade output configuration is used to reduce Miller capacitance and extend driving capability. To reduce the speed degradation caused by the ground inductance, a special but simple technique is employed while integrating the whole driver design. The laser driver is capable of driving 100mA modulation current with total power consumption, excluding the modulation current, of less than 140mW at 3.3V.
