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 …

A Linear Dynamic Voltage Scaling Technique With Adaptive Minimum Voltage Headroom Tracking for Implantable Neurostimulation

A Linear Dynamic Voltage Scaling Technique With Adaptive Minimum Voltage Headroom Tracking for Implantable Neurostimulation 150 150
Author(s): Kai Cui, Honglei Xu, Yingduo Duan, Yan Lu, Xiaoya Fan, Yanzhao Ma

Abstract:

This letter presents a linear dynamic voltage scaling (DVS) technique using a dual-loop multistage charge-pump maintaining the minimum voltage headroom for implantable neurostimulation. By adopting an analog DVS with adaptive feedback divider, the stimulus current source could be always kept operating at the boundary of the saturation region and the …
