Improved Analysis of Current-Steering DACs Using Equivalent Timing Errors
Daniel Beauchamp, Keith M. Chugg
Current-steering (CS) digital-to-analog converters (DACs) generate analog signals by combining weighted current sources. Ideally, the current sources are combined at each switching…

Linearization for High-Speed Current-Steering DACs Using Neural Networks
Daniel Beauchamp, Keith M. Chugg
This paper proposes a novel foreground linearization scheme for a high-speed CS-DAC. The technique leverages neural networks (NNs) to derive a LUT that maps the inverse of the DAC…

Machine Learning Based Image Calibration for a Twofold Time-Interleaved High Speed DAC
Daniel Beauchamp, Keith M. Chugg
In this paper, we propose a novel image calibration algorithm for a twofold time-interleaved DAC (TIDAC). The algorithm is based on simulated annealing, which is often used in the…
