A Low Quiescent Current Asynchronous Digital-LDO With PLL-Modulated Fast-DVS Power Management in 40 nm SoC for MIPS Performance Improvement
Yu-Huei Lee,Shen-Yu Peng,Chao-Chang Chiu,Alex Chun-Hsien Wu,Ke-Horng Chen,Ying-Hsi Lin,Shih-Wei Wang,Tsung-Yen Tsai,Chen-Chih Huang,Chao-Cheng Lee +9 more
TL;DR: A low quiescent current asynchronous digital- LDO (D-LDO) regulator integrated with a phase-locked loop (PLL)-modulated switching regulator (SWR) that achieves the near-optimum power management supply for core processor in system-on-chip (SoC).
Journal ArticleDOI
A Direct AC–DC and DC–DC Cross-Source Energy Harvesting Circuit with Analog Iterating-Based MPPT Technique with 72.5% Conversion Efficiency and 94.6% Tracking Efficiency
Shin-Hao Chen,Tzu-Chi Huang,Shao Siang Ng,Kuei-Liang Lin,Ming-Jhe Du,Yu-Chai Kang,Ke-Horng Chen,Chin-Long Wey,Ying-Hsi Lin,Chao-Cheng Lee,Jian-Ru Lin,Tsung-Yen Tsai +11 more
TL;DR: In this article, a cross-source energy (CSE) harvesting system accepts universal energy sources, including the ac and dc sources, automatically converts ac or dc input into dc output without being limited by the type of universal energy source.
Journal ArticleDOI
A Constant-on-Time Control DC–DC Buck Converter With the Pseudowave Tracking Technique for Regulation Accuracy and Load Transient Enhancement
Wen-Hau Yang,Chao-Jen Huang,Han-Hsiang Huang,Wei-Ting Lin,Ke-Horng Chen,Ying-Hsi Lin,Shian-Ru Lin,Tsung-Yen Tsai +7 more
TL;DR: In this paper, the pseudowave tracking (PWT) technique was proposed to reduce the load-dependent dc offset voltage of output load regulation while keeping the fast transient response similar to conventional COT buck converter with large ESR.
Proceedings ArticleDOI
20.2 Digital low-dropout regulator with anti PVT-variation technique for dynamic voltage scaling and adaptive voltage scaling multicore processor
Wen-Jie Tsou,Wen-Hau Yang,Jian-He Lin,Hsin Chen,Ke-Horng Chen,Chin-Long Wey,Ying-Hsi Lin,Shian-Ru Lin,Tsung-Yen Tsai +8 more
TL;DR: A DLDO regulator with an anti-PVT-variation technique permitting tradeoffs among the output voltage ripple, transient performance and load regulation is presented.
Journal ArticleDOI
Pseudo-Constant Switching Frequency in On-Time Controlled Buck Converter with Predicting Correction Techniques
Wei-Chung Chen,Hsin-Chieh Chen,Meng-Wei Chien,Ying-Wei Chou,Ke-Horng Chen,Ying-Hsi Lin,Tsung-Yen Tsai,Shian-Ru Lin,Chao-Cheng Lee +8 more
TL;DR: In this paper, the predicting correction technique (PCT) is proposed to achieve an adaptive on-time control for ripple-based buck converters. But, the PCT technique considers complete parasitic resistances of the components and devices.
