Journal ArticleDOI
Single-inductor multiple-output switching converters with time-multiplexing control in discontinuous conduction mode
TL;DR: In this article, an integrated single-inductor dual-output boost converter is presented, which adopts time-multiplexing control in providing two independent supply voltages (3.0 and 3.6 V) using only one 1/spl mu/H off-chip inductor and a single control loop.
Journal ArticleDOI
A pseudo-CCM/DCM SIMO switching converter with freewheel switching
TL;DR: In this paper, a single-independant multiple-output (SIMO) boost converter was proposed to handle large load currents with a much smaller current ripple, while retaining low cross regulation.
Journal ArticleDOI
Analysis and Design Strategy of UHF Micro-Power CMOS Rectifiers for Micro-Sensor and RFID Applications
TL;DR: A superposition method is proposed to optimize the performance of multiple-output rectifiers and Constant-power scaling and area-efficient design are discussed.
Journal ArticleDOI
A 13.56 MHz Wireless Power Transfer System With Reconfigurable Resonant Regulating Rectifier and Wireless Power Control for Implantable Medical Devices
TL;DR: Two novel backscattering uplink techniques are proposed for fast and energy-efficient data feedback for general data transmission using Manchester code and for fast duty cycle feedback to cater for fast load-transient responses.
Journal ArticleDOI
Integrated Low-Loss CMOS Active Rectifier for Wirelessly Powered Devices
TL;DR: A low-loss CMOS full-wave active rectifier that consists of two dynamically biased and symmetrically matched active diodes each realized by an nMOS switch driven by a 2-ns voltage comparator with reverse-current control is presented.
