DOI: 10.1088/1748-0221/18/04/c04009
Abstract: A line driver with configurable pre-emphasis is implemented in a 65 nm CMOS process. The driver utilizes a three-tap feed-forward equalization architecture. The relative delays between the taps are selectable in increments of 1/16th of the… read more here.

DOI: 10.1109/tcsi.2017.2763581
Abstract: This paper analyzes and compares two popular methods to widen the modulation bandwidth of a phase-locked loop, i.e., the pre-emphasis and the two-point injection technique. The analysis reveals that both architectures have the same sensitivity… 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.
