Multi-gigabit analog equalizers for plastic opticalfibers
Two new CMOS analog continuous-time equalizers for high-speed short-haul optical fiber communications are presented in this paper. The proposed structures compensate the limited bandwidth-length product of 1-mm SI-POF channels (45MHz100m) and have been designed in a standard 0.18-?m CMOS process. The equalizers are aimed for multi-gigabit short-range applications, targeting up to 2Gb/s through a 50-m SI-POF. The prototypes operate with a single supply voltage of only 1V and overcome the severe limitations suffered by the widely used degenerated differential pair due to the low supply voltage.
