Non-shaping dynamic element matching (DEM) randomization schemes are widely adopted for wideband Nyquist-rate digital-to-analog converters (DACs) within transmitter architectures. Here, randomization translates the mismatch-induced distortion into wh

This paper presents the design of a low-latency, highly linear current-steering DAC for use in continuous-time ADCs. A detailed analysis of equivalent unary-weighted current-steering DAC topologies in terms of mismatch, noise, and output-impedance re

In the domain of computer vision, entropy—defined as a measure of irregularity—has been proposed as an effective method for analyzing the texture of images. Several studies have shown that, with specific parameter tuning, entropy-based approaches

Two-dimensional fuzzy entropy, dispersion entropy, and their multiscale extensions (MFuzzyEn2D and MDispEn2D, respectively) have shown promising results for image classifications. However, these results rely on the selection of key parameters that ma

In deep metric learning (DML), high-level input data are represented in a lower-level representation (embedding) space, such that samples from the same class are mapped close together, while samples from disparate classes are mapped further apart. In

Gene expression was analyzed in five pairs of 5-fluorouracil (5-FU) resistant and parental cancer cell lines on DNA microarrays. In unsupervised analysis, a prediction rule was built from the expression profiles of 29 genes, and 5-FU sensitivity clas

This paper presents a programmable amplitude and timing error shaping bandpass dynamic- element-matching (DEM) for Nyquist-rate D/A converters. Amplitude and timing-skew errors are shaped using two different loop-filters employed within the DEM struc
