High-Gain Wide-Bandwidth Capacitor-Less Low-Dropout Regulator (LDO) for Mobile Applications Utilizing Frequency Response of Multiple Feedback Loops
Sung-Wan Hong,Gyu-Hyeong Cho +1 more
TL;DR: This paper presents a novel capacitor-less low-dropout regulator (LDO) for mobile applications that utilizes multiple feedback loops to satisfy several design challenges for some mobile applications which were not considered in the previous capacitor- less LDOs.
Journal ArticleDOI
High-Efficiency Hybrid Dual-Path Step-Up DC–DC Converter With Continuous Output-Current Delivery for Low Output Voltage Ripple
TL;DR: In this paper, the authors proposed a dual-path step-up dc-dc converter (DPUC), which has a hybrid structure using one inductor and one flying capacitor to make dual current delivery paths.
Journal ArticleDOI
Double Pile-Up Resonance Energy Harvesting Circuit for Piezoelectric and Thermoelectric Materials
TL;DR: The proposed harvester operates in a double pile-up mode (DPM) to efficiently extract energy from PZT with the enhanced damping force, resulting in a 1452% improvement in power extraction, which is the best performance among the state-of-the-art works.
Journal ArticleDOI
A Noninverting Buck–Boost Converter With State-Based Current Control for Li-ion Battery Management in Mobile Applications
TL;DR: The state-based buck–boost converter enables seamless mode transition and stable output regulation with fixed interleaving patterns even when input and output voltages are similar, ensuring robust mode change with inherent hysteresis.
Journal ArticleDOI
