Low-Power SAR ADCs: Basic Techniques and Trends

IEEE Open Journal of the Solid-State Circuits Society, 2022
With the advent of small, battery-powered devices, power efficiency has become of paramount importance. For analog-to-digital converters (ADCs), the successive approximation register (SAR) architecture plays a prominent role thanks to its ability to combine power efficiency with a simple architecture, a broad application scope, and technology ...

Optimized Reduced Field of View and Fat Suppression Methods for Interleaved Multislice In Vivo Cardiac Diffusion Tensor Imaging

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1097-1110, September 2026.
ABSTRACT Purpose Slice interleaving, a limited phase encode (PE) field of view (FOV), and effective fat suppression are vital for efficient cardiac diffusion tensor imaging (cDTI) with minimal artifacts. This study aimed to optimize reduced FOV and fat suppression methods for interleaved multislice cDTI to improve signal‐to‐noise ratio (SNR) and ...

SNR‐Efficient Inhomogeneous Magnetization Transfer (ihMT) for Clinical Applications at 7 T

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1162-1177, September 2026.
ABSTRACT Purpose Inhomogeneous MT (ihMT) is an MRI modality sensitive to Myelin, the lipid‐rich membrane surrounding the axons. A novel ihMT saturation strategy and its associated B1+ correction at UHF are proposed. The aim is to generate a strong ihMT effect within a clinically compatible scan time while complying with SAR constraints at 7 T.

Microcontroller Power Consumption Measurement Based on PSoC

Telfor Journal, 2016
Microcontrollers are often used as central processing elements in embedded systems. Because of different sleep and performance modes that microcontrollers support, their power consumption may have a high dynamic range, over 100 dB.

Unveiling Lactylation: A Novel Frontier in Cancer Stemness and Therapy

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Tumor metabolism and epigenetic regulation are intrinsically linked. This review highlights lactylation as a pivotal bridge connecting these processes, acting as an active epigenetic effector in cancer stemness. We delineate how lactylation orchestrates the cancer stem cell landscape and evaluate its regulatory networks.

Low-power SAR ADCs: trends, examples and future

ESSCIRC 2019 - IEEE 45th European Solid State Circuits Conference (ESSCIRC), 2019
With the development of mobile devices and Internet-of-Things,the demand for low-power circuits has been growing rapidly. The Analog-to-Digital Converter (ADC) is a key building block in these systems. In this work,we review the progress of low-power ADCs over the years in terms of performance and limitations. From these limitations,it can be shown why

The past, the present, and the future of preclinical mouse models for Alzheimer's disease and related dementias

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract Over the past decade, the Model Organism Development and Evaluation for Late‐Onset Alzheimer's Disease (MODEL‐AD) consortium has transformed preclinical Alzheimer's disease (AD) research by addressing critical limitations in traditional mouse models that failed to translate to human disease.

Noise shaping in SAR ADC

Facta universitatis - series: Electronics and Energetics, 2020
The successive approximation register (SAR) analog-to-digital converter (ADC) is currently the most popular type of ADC architecture, owing to its power efficiency. They are also used in multichannel systems, where power efficiency is of high importance because of the large number of simultaneously working channels.

Genomic, Trop‐2, and Immune Profiles of Carcinomatous and Sarcomatous Components in Ovarian Carcinosarcoma

Cancer Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Ovarian carcinosarcoma (OCS) is a rare, aggressive tumor composed of both carcinomatous and sarcomatous components, typically associated with poor prognosis. Due to its rarity, the molecular characteristics, immune microenvironment, and optimal treatment of OCS remain unclear.

Consistent Quadratic Phase Formation in 3D Fast Spin Echo Using Frequency‐Modulated RF Pulses

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 666-681, August 2026.
ABSTRACT Purpose Frequency‐modulated (FM) RF pulses achieve broadband excitation with low RF peak power, which is required in MRI with inhomogeneous magnetic fields. However, the quadratic phase generated with FM pulses makes it difficult to use them in fast spin echo (FSE), because even and odd refocused echoes have different spatial phase profiles ...
