Author(s): Xiudeng Wang, Haohao Shi, Youlan Zeng, Libo Qian, Yang Liu, Guangqian Zhu, Yongyuan Li, Zhangming Zhu

Abstract:

This article presents a rectifierless synchronous inversion and optimal charge extraction (SIOCE) interface with single-stage maximum power point tracking (MPPT) for intermittent vibrations, which are common in real-world applications. Unlike conventional rectifiers that suffer from standby power consumption or rely on inefficient multi-stage conversion, the proposed SIOCE interface circuit decouples …

A 0.73 A/mm3 Switched-Capacitor-Stack-Inductor Volumetric Integrated Voltage Regulator With Auxiliary-Assisted Gain Boosting for High-Power-Density PoL Applications 150 150
Author(s): Xuliang Wang, Renwei Chen, Haoyu Wang, Yang Liu, Wing-Hung Ki, Yan Wang, Xiaosen Liu

Abstract:

This article presents a volumetric integrated voltage regulator (IVR) based on a switched-capacitor-stack-inductor (SCSL) architecture that employs a holistic topology-control-package codesign to overcome the hardware and efficiency bottlenecks of conventional asymmetric multiinductor designs. Based on a discrete-time state-space model, a rigorous root-locus analysis reveals that a rudimentary single voltage-mode control …

A 12-bit 1-GS/s Current-Steering DAC With Paired Current Source Switching Background Mismatch Calibration

A 12-bit 1-GS/s Current-Steering DAC With Paired Current Source Switching Background Mismatch Calibration 150 150
Author(s): Chang-Un Park, Jae-Hyun Chung, Chunsuk Kim, Hyun-Woo Shin, Charlie Tahar, Seung-Tak Ryu

Abstract:

This article presents a spur-suppressed background calibration technique for high-speed current-steering digital-to-analog converters (DACs), based on a paired current source (CS) switching scheme. In conventional background calibration, periodic switching of CSs to and from the calibration mode introduces unwanted glitches that appear as spurious tones. The proposed technique introduces an …

A Two-Stage 12–1-V Converter Featuring Regulated Resonant SC Regulators and Collaborative Control Scheme

A Two-Stage 12–1-V Converter Featuring Regulated Resonant SC Regulators and Collaborative Control Scheme 150 150
Author(s): Shengdao Ren, Yukan Du, Menglian Zhao, Zhichao Tan, Chushan Li, Yong Ding, Wuhua Li, Wanyuan Qu

Abstract:

In the field of power converters for data centers, the two-stage architecture has received widespread attentions due to its various advantages. Especially, the switched-capacitor voltage regulator (SCVR) becomes popular as the second-stage converter owing to its high efficiency and power density. However, the SCVR suffers from poor voltage regulation and …

A Fast Transient Response Fully Integrated LDO With a Novel Resetting Oscillator Control Method

A Fast Transient Response Fully Integrated LDO With a Novel Resetting Oscillator Control Method 150 150
Author(s): Masoud Kargaran, Amir Besharati Rad, Ali Medi

Abstract:

This article introduces a novel resetting oscillator regulator (ROR) control method for low-dropout (LDO) regulators, designed to achieve fast settling times for both load and reference input steps. The proposed ROR integrates a high-speed loop that independently functions as an oscillator in a closed-loop configuration, along with a separate high-rate …
