Architecture Design for Rise/Fall Asymmetry Glitch Minimization in Current-Steering DACs
Ramin Babaee, Shahab Oveis Gharan, Martin Bouchard
Current-steering digital-to-analog converter (DAC) is a prominent architecture that is commonly used in high-speed applications such as optical communications. One of the shortcomi…
Timing-Error Optimized Architecture for Current-Steering DACs
Ramin Babaee, Shahab Oveis Gharan, Martin Bouchard
We propose a novel digital-to-analog converter (DAC) weighting architecture that statistically minimizes the distortion caused by random timing mismatches among current sources. To…
Current-Steering DAC Architecture Design for Amplitude Mismatch Error Minimization
Ramin Babaee, Shahab Oveis Gharan, Martin Bouchard
We propose a novel digital-to-analog converter (DAC) weighting architecture that statistically minimizes the distortion caused by random current mismatches. Unlike binary, thermome…
Joint Precoding and Probabilistic Constellation Shaping using Arithmetic Distribution Matching
Babaee Ramin, Oveis Gharan Shahab, Bouchard Martin
The problem of joint shaping and precoding is studied in this paper. We introduce statistical dependencies among consecutive symbols to shape the constellation while minimizing the…
