| 1 | A comparative study of digital low dropout regulators显示文摘Granular power management in a power-efficient system on a chip(SoC)requires multiple integrated voltage regulators with a small area,process scalability,and low supply voltage.Conventional on-chip analog low-dropout regulators(ALDOs)can hardly meet these requirements,while digital LDOs(DLDOs)are good alternatives.However,the conventional DLDO,with synchronous control,has inherently slow transient response limited by the power-speed trade-off.Meanwhile,it has a poor power supply rejection(PSR),because the fully turned-on power switches in DLDO are vulnerable to power supply ripples.In this comparative study on DLDOs,first,we compare the pros and cons between ALDO and DLDO in general.Then,we summarize the recent DLDO advanced techniques for fast transient response and PSR enhancement.Finally,we discuss the design trends and possible directions of DLDO. | Mo Huang Yan Lu Rui P.Martins | 2020 | Journal of Semiconductors2020，41，11： | 1 |
| 2 | Ring-VCO-based phase-locked loops for clock generation–design considerations and state-of-the-art显示文摘This article overviews the design considerations and state-of-the-art of the ring voltage-controlled oscillator(VCO)-based phase-locked loops(PLLs)for clock generation in different applications.Partic-ularly,the objective of the current work is to evaluate the required PLL performance among the fundamental metrics of power,jitter and area.An in-depth treatment of the mainstream PLL architectures and the associated design techniques enables them to be compared analyt-ically and benchmarked with respect to their figure-of-merit(FoM).The paper also summarizes the key concerns on the selection of dif-ferent circuit techniques to optimize the clock performance under dif-ferent scenarios. | Shiheng Yang Jun Yin Yueduo Liu Zihao Zhu Rongxin Bao Jiahui Lin Haoran Li Qiang Li Pui-In Mak Rui P.Martins | 2023 | Chip2023，2，2： | 0 |
| 3 | Recent advancements in continuously scalable conversion-ratio switched-capacitor converter显示文摘Switched-capacitor(SC)DC-DC converter[1]is an impor-tant alternative to inductive DC-DC converter,in terms of removing the bulky power inductor.Hence,it is widely used in low-profile,low-power applications,such as the internet of things(IoT)sensor nodes and energy harvesting[2].Mean-while,considering that capacitor has a much higher energy density than inductor,high-power applications. | Mo Huang Yuanfei Wang Rui P.Martins Yan Lu | 2024 | Journal of Semiconductors2024，45，4： | 0 |
