Abstract: A 10 Gb/s PAM-4 transmitter (TX) with a modulo-based equalization technique is presented. The proposed feed-forward Tomlinson-Harashima precoding (FF-THP) scheme takes advantage of both Tomlinson-Harashima precoding (THP) and feed-forward equalization (FFE). The vertical eye margin… read more here.

DOI: 10.1109/jssc.2022.3192711
Abstract: This article presents a 56-Gb/s four-level pulse amplitude modulation (PAM-4) transmitter/receiver (TX/RX) chipset for optical link. The optical transmitter (TX) adopts a digital-to-analog converter (DAC)-based structure with a two-tap nonlinear PAM-4 feed-forward equalizer (FFE) implemented… read more here.

DOI: 10.1109/tcsii.2019.2922040
Abstract: We demonstrate a 40-Gb/s PAM-4 transmitter having 2-tap pre-emphasis, whose power consumption is significantly reduced by the use of toggling serializers. In addition, a new type of PAM-4 source-series terminated driver is proposed, which enables… read more here.
