A 10-Bit 400-KS/s Low Noise Asynchronous SAR ADC with Dual-Domain Comparator for Input-Referred Noise Reduction [PDF]

open access: yesSensors, 2022
This paper presents a low noise 0.6-V 400-kS/s asynchronous successive approximation register (SAR) analog-to-digital converter (ADC) for input-referred noise reduction. A dual-domain comparator is proposed to optimize the power, noise, and sampling rate

A Hybrid Energy-Efficient, Area-Efficient, Low-Complexity Switching Scheme in SAR ADC for Biosensor Applications [PDF]

open access: yesMicromachines, 2023
A hybrid energy-efficient, area-efficient, low-complexity switching scheme in SAR ADC for biosensor applications is proposed. This scheme is a combination of the monotonic technique, the MSB capacitor-splitting technique, and a new switching method.

Mitigating banding artifacts in balanced steady‐state free precession using parallel transmission in a single acquisition [PDF]

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 1017-1029, February 2026.
Abstract Purpose Using parallel transmission (pTx) in ultra‐high field MRI allows efficient radiofrequency pulse designs that can produce uniform excitations. Here, we demonstrate that pTx can simultaneously mitigate B1+$$ {\mathrm{B}}_1^{+} $$ non‐uniformity and off‐resonance artifacts in balanced steady‐state free precession sequences at 7 T.

Complementarity of BOLD and ADC‐fMRI in Mapping Brain Visual Processing in the Rat [PDF]

open access: yesNMR in Biomedicine, Volume 39, Issue 3, March 2026.
BOLD‐fMRI and ADC‐fMRI were acquired at 9.4 and 14 T during visual stimulation with variable frequency. BOLD‐fMRI showed robust positive/negative responses but depended on regional vascularization patterns. ADC‐fMRI was able to detect neural activity independently from vascular effects at 9.4 T.
