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,

A New Successive Time Balancing Time-to-Digital Conversion Method
Sensors, 2023 This paper presents a new self-clocked time-to-digital conversion method based on a binary successive approximation (SA) algorithm. Its novelty consists in combining fully clockless operation with direct conversion of the measured time interval. The lack

A Photonic Digitization Scheme With Enhanced Bit Resolution Based on Hierarchical Quantization
IEEE Access, 2020 The major limitation of the photonic digitization schemes based on the phase-shifting of modulation transfer function lies in its relatively low bit resolution, which is log2(2N ), where N is the number of optical channels or modulators.

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.

Reconfigurable Analog Preprocessing for Efficient Asynchronous Analog-to-Digital Conversion
Journal of Low Power Electronics and Applications, 2019 Wearable medical devices, wireless sensor networks, and other energy-constrained sensing devices are often concerned with finding specific data within more-complex signals while maintaining low power consumption. Traditional analog-to-digital converters (
