Abstract :
A high modulation efficiency laser diode/modulator driver (LDD/MD) is designed for low-cost optical access networks using shunt peaking active inductors and direct-coupled topology to boost the bandwidth, to improve modulation efficiency, and to reduce the silicon area. It provides a maximum modulation current of 74 mA or a maximum modulation voltage of 3.9 V through an equivalent 50 Omega load. Fully-open optical eye diagrams were observed at bit rate up to 1.25-Gb/s when it used as a LDD or a MD. The maximum RMS jitter is 38 ps. The 0.4 mm2 chip consumes only 470 mW in 5 V 0.6 mum standard CMOS.
