A 16 Bit 125 MS/s Pipelined Analog-to-Digital Converter with a Digital Foreground Calibration Based on Capacitor Reuse

A 16-bit 125 MS/s pipelined analog-to-digital converter (ADC) implemented in a 0.18 μm CMOS process is presented in this paper. A sample-and-hold amplifier-less (SHA-less) modified 2.5-bit front-end is adopted, which splits the sampling capacitor in ...

Study of the Operating Conditions for a Referenced Contactless Conductivity Detector for Capillary Zone Electrophoresis

ELECTROPHORESIS, EarlyView.
A referenced contactless conductivity detector will lead to corrupted electropherograms if care is not taken to set it up correctly. ABSTRACT The capacitively coupled contactless conductivity detector features a reference channel for the suppression of the signal caused by the background conductivity and high voltage excitation for a good signal‐to ...

Spatiotemporal engineering of dynamic color in alternating‐current‐driven light‐emitting devices

FlexMat, EarlyView.
This review presents a mechanism‐driven framework for spectral tuning in alternating‐current‐driven light‐emitting devices, systematically integrating emissive center engineering, device architecture design, and driving signal modulation. By linking microscopic carrier dynamics and electric‐field‐charge interactions with macroscopic spectral evolution,

Chronic Prostatitis/Chronic Pelvic Pain Syndrome: Research Progress and Precision Diagnosis‐Therapy Under the Integrated Neuro–Immune–Metabolic–Microbiota Axis Framework

iMetaMed, EarlyView.
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is increasingly recognized as a systemic disorder rather than a purely local prostate disease. The diagram illustrates the transition from the traditional local prostate‐centered model to a multi‐axis systemic framework involving clinical heterogeneity, local prostatic inflammation, systemic ...

Multi‐command wearable magnetic human‐machine interface enabled by low‐noise sensing and time‐series deep learning

InfoScience, EarlyView.
This study integrates a wrist‐worn sensing platform based on a low‐noise planar Hall magnetoresistive sensor with time‐series deep learning to enable long‐range, single‐sensor, multi‐command gesture recognition with high accuracy. Further evaluations show reliable generalization across different days, previously unseen users, wearing‐position ...
