Wideband Continuous-Time MASH ADCs: Principles, Challenges, and Prospects

IEEE Open Journal of the Solid-State Circuits Society
Continuous-time (CT) delta-sigma modulator (DSM) is a popular choice for its inherent aliasing and resistive input impedance characteristics. With the increased demands for wide-bandwidth (BW) and high-dynamic range (DR), multistage noise shaping (MASH ...

Programmable broadband optical field spectral shaping with megahertz resolution using a simple frequency shifting loop

Nature Communications, 2019
Full spectral and temporal control of light has a multitude of applications but is often limited in frequency resolution. The authors implement a scheme using a frequency shifting optical loop for optical field spectral shaping with a high degree of ...

Nuclear morphology is shaped by loop-extrusion programs

Nature
It is well established that neutrophils adopt malleable polymorphonuclear shapes to migrate through narrow interstitial tissue spaces1-3. However, how polymorphonuclear structures are assembled remains unknown4. Here we show that in neutrophil progenitors, halting loop extrusion-a motor-powered process that generates DNA loops by pulling in chromatin5 ...

Robust Control for a Battery Charger Using a Quadratic Buck Converter

IEEE Access
In this paper, the quadratic buck converter (QBC) is proposed as competitive alternative to implement a battery charger. Since QBC is a high order system, the required control is designed to follow the conventional constant-current constant-voltage ...

Optimal Placement of H∞ Loop Shaping Damping Controller Using Dynamic Relative Gain Array

IEEE Access
Low-damping inter-area oscillation is a severe problem for the smooth operation of the interconnected power system. These oscillations are observed due to the bulk power transmission from one area to another through a weak tie line.
