Yue, X. (author), Mo, J. (author), Chen, Zhiyuan (author), Vollebregt, S. (author), Zhang, Kouchi (author), Du, S. (author)Synchronized rectifiers offer promising solutions for piezoelectric energy harvesting; however, achieving the promised energy extraction performance necessitates using either a bulky inductor or multiple large capacitors, which cannot be on-chip integrated and increase the system form factor. This article introduces a fully integrated...journal article 2024

Lu, Qi (author), Li, Shuangmu (author), Zhao, Bo (author), Jiang, Junmin (author), Chen, Zhiyuan (author), Du, S. (author)Multiple voltage conversion ratio (VCR) recursive switched-capacitor (SC) dc-dc converters, based on several basic 2:1 converters, are widely used for on-chip power supplies due to their flexible VCRs for higher energy efficiency. However, conventional multiple VCR SC converters usually have one or more 2:1 converters unused for some VCRs,...journal article 2023

Yue, X. (author), Chen, Zhelun (author), Zou, Yiwei (author), Du, S. (author)Ultrasonic wireless power transfer (WPT) has been proved to be a promising approach to power biomedical implants. To extract the energy generated from the transducer, a rectifier is typically required. Previous inductor-based rectifiers (SSHI and SECE) require a large off-chip inductor to achieve good performance, which is not desired for...conference paper 2022
