Abstract
Limitations in data transmission caused by modal dispersion in fiber-optic links can be significantly improved using equalization techniques. In this paper, two different equalizer implementation approaches are proposed to extend the transmission capacities of existing fiber-optic links. The building blocks of the equalizer including a multiplier cell, a delay line, and an output buffer stage are fully integrated on a 0.18-μm CMOS process. For the continuous-time tap-delay implementation, a passive LC delay line and an active inductance peaking delay line are compared for performance against process variation, as well as power consumption. In addition, a delay-locked loop is proposed to counter delay variations caused by changes in the process corner. A 10-Gb/s nonreturn-to-zero signal is received after transmission through a 500-m multimode-fiber channel, and the signal impairment due to the differential modal delay is successfully compensated using both feed-forward equalizers.
