Multi-level pre-equalization using analog FIR filters based on 28-nm FD-SOI for 20-Gb/s 4-PAM multi-mode fiber transmission

We propose a novel multi-level pre-equalizer composed of multiple binary analog FIR filters, which achieves cost-effectiveness and low power consumption. The performance was investigated using 28-nm FD-SOI based CMOS circuits for 20-Gb/s 4-PAM MMF transmission.
