A High-Efficiency Low-Cost Multi-Antenna Energy Harvesting System With Leakage Suppression 150 150
Author(s): Zhaobo Zhang, Chenchang Zhan, Shuangxing Zhao, Man-Kay Law

Abstract:

This article presents a multi-antenna RF energy harvester (MARFEH) with leakage suppression to achieve high output power and avoid the effects of interference and blind spots in the room, and all the RF rectifiers share only one buffering capacitor to achieve low cost. The proposed leakage-suppressed rectifier utilizing adaptive $V_{…

A Single-Stage Dual-Output Regulating Voltage Doubler for Wireless Power Transfer
A Single-Stage Dual-Output Regulating Voltage Doubler for Wireless Power Transfer 150 150
Author(s): Tianqi Lu, Kofi A. A. Makinwa, Sijun Du

Abstract:

A single-stage dual-output regulating voltage doubler (DOVD) is proposed for biomedical wireless power transfer (WPT) systems. Derived from the full-wave voltage doubler (VD) topology, it achieves ac-to-dc rectification and dual-output voltage regulation in a single stage by using only two power transistors. The DOVD’s inherent voltage conversion ratio (VCR) …

Analysis and Design of a 10.4-ENOB 0.92–5.38- $\mu$ W Event-Driven Level-Crossing ADC With Adaptive Clocking for Time-Sparse Edge Applications
Analysis and Design of a 10.4-ENOB 0.92–5.38- $\mu$ W Event-Driven Level-Crossing ADC With Adaptive Clocking for Time-Sparse Edge Applications 150 150
Author(s): Jonah Van Assche, Georges Gielen

Abstract:

Level-crossing ADCs (LCADCs) operate on changes in the input signal, resulting in an event-driven power consumption and data output. For signals with time-sparse activity (e.g., neural action potentials, and ECG), such ADCs can offer advantages at the system level through the reduced data rate that decreases the transmission and/…
