A Modulo-Based Architecture for Analog-to-Digital Conversion [PDF]
IEEE Journal on Selected Topics in Signal Processing, 2018 Systems that capture and process analog signals must first acquire them through an analog-to-digital converter. While subsequent digital processing can remove statistical correlations present in the acquired data, the dynamic range of the converter is ...

Deep Task-Based Analog-to-Digital Conversion [PDF]
IEEE Transactions on Signal Processing, 2022 Analog-to-digital converters (ADCs) allow physical signals to be processed using digital hardware. Their conversion consists of two stages: Sampling, which maps a continuous-time signal into discrete-time, and quantization, i.e., representing the continuous-amplitude quantities using a finite number of bits.

Multistep optimal analog-to-digital conversion
IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2005 An important aspect of analog-to-digital conversion is the impact of quantization errors. This paper outlines how finite horizon constrained optimization methods can be utilized to design converters which minimize a weighted measure of the quantization distortion. We propose a novel converter, which can be implemented as a feedback loop. It embeds /spl

Blind Modulo Analog-to-Digital Conversion [PDF]
IEEE Transactions on Signal Processing, 2022 In a growing number of applications, there is a need to digitize signals whose spectral characteristics are challenging for traditional Analog-to-Digital Converters (ADCs). Examples, among others, include systems where the ADC must acquire at once a very wide but sparsely and dynamically occupied bandwidth supporting diverse services, as well as ...

Control-Bounded Analog-to-Digital Conversion [PDF]
Circuits, Systems, and Signal Processing, 2021 AbstractA control-bounded analog-to-digital converter consists of a linear analog system that is subject to digital control, and a digital filter that estimates the analog input signal from the digital control signals. Such converters have many commonalities with delta–sigma converters, but they can use more general analog filters.

Expansion of dynamic range of sampling and storage device by weight integration of narrow-band oscillation [PDF]
Омский научный вестник, 2021 The most bottleneck of high-frequency digital radio receivers in terms of dynamic characteristics is the process of analog-to-digital conversion. Most often, to meet the requirements for the speed and dynamic range of the analog-to-digital conversion,
