Abstract: This article presents a 128-Gb/s current-mode four-level pulse amplitude modulation (PAM-4) transmitter (TX) with a pre-emphasis asymmetric fractional-spaced feed-forward equalizer (AFS-FFE) ...
Abstract: Herein, the analog-based, 2-tap feed-forward equalization (FFE) voltage-mode transmitter using dual supply/ground voltage regulation is presented. In an FFE data modulator, the data are ...
