A 3.5 to 4.7-GHz Fractional-N ADPLL With a Low-Power Time-Interleaved GRO-TDC of 6.2-ps Resolution in 65-nm CMOS Process

open access: yesIEEE Access
This paper proposes a low-power design method and a low-noise phase offset calibration technique for a gated ring-oscillator time-to-digital converter (GRO-TDC), which normally consumes a large percentage of most all-digital phase-locked loop (ADPLL ...

Stray Magnetic Field Compensation with a Scalar Atomic Magnetometer

open access: yes, 2010
We describe a system for the compensation of time-dependent stray magnetic fields using a dual channel scalar magnetometer based on non-linear Faraday rotation in synchronously optically pumped Cs vapour.

Structure‐Dependent Resonant Frequency Engineering of Textile Tactile Sensors Toward Rapid and Precise Braille Recognition Surpassing Human Sensation

open access: yesAdvanced Science, EarlyView.
A resonant frequency engineering strategy is proposed to modulate the sensibility of piezoresistive textile‐based tactile sensor. It achieves simultaneous detection of static pressure and dynamic vibrations across an unprecedented bandwidth of 5–600 Hz, surpassing human sensation, therefore enables rapid and precise braille recognition.

Phase Locked Loop Test Methodology [PDF]

open access: yes, 2008
Phase locked loops are incorporated into almost every large-scale mixed signal and digital system on chip (SOC). Various types of PLL architectures exist including fully analogue, fully digital, semi-digital, and software based.

An On‐Demand Neuromorphic Vision System Enabled by a Multi‐Paradigm Neuromorphic Device and Hierarchical Reconfigurability Designed from Device to System Level

open access: yesAdvanced Science, EarlyView.
An on‐demand ultra‐reconfigurable intelligent vision system with hierarchical reconfigurability from device to system levels is demonstrated. Through co‐design of a multi‐paradigm device, reconfigurable circuits, and adaptive system architecture/algorithms, the system enables seamless switching among spiking, non‐spiking, neuromorphic imaging (NI), and

The Dynamical Hypothesis in Situ: Challenges and Opportunities for a Dynamical Social Approach to Interpersonal Coordination

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract Over the past three decades, Van Gelder's dynamical hypothesis has been instrumental in reconceptualizing the ways in which perception‐action‐cognition unfolds over time and in context. Here, I examine how the dynamical approach has enriched the theoretical understanding of social dynamics within cognitive science, with a particular focus on ...

A Digitally Controlled Injection-Locked Oscillator With Fine Frequency Resolution

open access: yesIEEE Journal of Solid-State Circuits, 2016
We propose a digitally controlled injection-locked RF oscillator with an auxiliary loop as an alternative to the conventional capacitive fine-tuning of an LC-tank. The oscillator is injection locked to a time-delayed version of its resonating voltage and
