One-Cycle-Balance Control in Buck Converters for Consecutive Load-Step Events

One-Cycle-Balance Control in Buck Converters for Consecutive Load-Step Events 150 150
Author(s): Zihao Tang, Jiacheng Yang, Rui P. Martins, Mo Huang

Abstract:

One-cycle-balance (OCB) response represents the optimal load-transient response for buck converters, maximizing system energy efficiency and robustness. While prior art has demonstrated OCB response for single load-step events, it fails in consecutive transients, which are prevalent in modern applications. This work overcomes these limitations by introducing an OCB controller that …

A Wide-Lock-in-Range and Fast-Settling-Time, 11.6-to-14-GHz SSPLL With an Event-Driven FLL and a Low-Power Harmonic-Lock Detector

A Wide-Lock-in-Range and Fast-Settling-Time, 11.6-to-14-GHz SSPLL With an Event-Driven FLL and a Low-Power Harmonic-Lock Detector 150 150
Author(s): Youngjun Kim, Siheon Lee, Taehyub Kim, Sunhaeng Heo, Younghyun Lim

Abstract:

This article presents a wide-lock-in-range and fast-settling-time, 11.6-to-14-GHz subsampling phase-locked loop (PLL) subsampling PLL (SSPLL) using an event-driven frequency-locked loop (ED-FLL) and a harmonic-lock detector (HLD). The ED-FLL becomes active only when a frequency disturbance, $f_{\mathrm {D}}$ , is detected, rapidly corrects the frequency error using a lock-expedition algorithm, …

A 96 × 64 SPAD LiDAR Sensor With 6× Imaging FoM Promotion by AI-Assisted Fusion of 2-D and Edge-Guided Sparse 3-D Detection

A 96 × 64 SPAD LiDAR Sensor With 6× Imaging FoM Promotion by AI-Assisted Fusion of 2-D and Edge-Guided Sparse 3-D Detection 150 150
Author(s): Bu Chen, Qi Zheng, Zikun Cai, Hankun Lv, Jingyi Wang, Jun Han, Zhangcheng Huang, Jianlu Wang, Qi Liu, Ming Liu

Abstract:

Flash-mode direct time-of-flight (dToF) light detection and ranging (LiDAR) is widely adopted in autonomous systems and robotics due to its capability for accurate depth measurement and robustness under challenging lighting conditions. However, scaling single-photon avalanche diode (SPAD)-based dToF pixel arrays toward higher resolution 3-D imaging introduces significant challenges in …

A Single-Lead ECG Wearable Sensor With 1.04 s Latency for Cardiac and Biometric Detection Tasks

A Single-Lead ECG Wearable Sensor With 1.04 s Latency for Cardiac and Biometric Detection Tasks 150 150
Author(s): Yuxin Ji, Chao Wang, Yuzhi Hao, Yang Zhao, Jian Zhao, Mingyi Chen, Guoxing Wang, Yong Lian, Yongfu Li

Abstract:

The wearable electrocardiogram (ECG) sensor has immense potential for cardiovascular healthcare monitoring. However, uploading ECG signals to server-side devices for diagnosis poses privacy risks. Multi-tasking ECG processors rely on multi-beat windows and complex models, leading to high latency and energy consumption that limit deployment in resource-constrained wearable devices. In this …

PANDA: A Reconfigurable Seizure Prediction and Detection Neural Network Accelerator for Epilepsy Monitoring

PANDA: A Reconfigurable Seizure Prediction and Detection Neural Network Accelerator for Epilepsy Monitoring 150 150
Author(s): Siyuan Qiu, Xiaoyi Song, Xiangjie Song, Changchun Zhou, Xiaoyan Song, Jie Yang, Wenjin Wang, Yuchao Yang, Hailong Jiao

Abstract:

For effective healthcare management of epilepsy patients in a non-hospital environment, continuous monitoring of EEG signals is crucial, where wearable intelligent devices are essential. The existing seizure monitoring devices, however, cannot achieve high sensitivity, a short detection latency, a low false alarm rate (FAR), as well as ultra-low-power computing simultaneously. …

GUARD: A Clock and Voltage Glitch Detector With On-Demand Protection

GUARD: A Clock and Voltage Glitch Detector With On-Demand Protection 150 150
Author(s): Mao Li, Sanu K. Mathew, Vivek De, Mingoo Seok

Abstract:

This article presents GUARD, a fully digital, variation-tolerant detector for clock and voltage glitch attacks, featuring an integrated on-demand protection mechanism. Fabricated in 28-nm CMOS, GUARD provides robust security for digital systems by monitoring the system clock for maliciously injected faults. It employs a pair of optimized time-to-digital converters (TDCs) …
