中文摘要

本文提出了一种堆叠MOSFET驱动(SMD)技术,旨在解决低压器件在构建堆叠结构时面临的瞬态响应差或占用面积大的问题。该技术利用自稳定特性有效驱动功率级,显著降低了开关节点的噪声,从而实现了低静态电流和优异的交叉调节性能。

English Abstract

Stacked mosfet structures made of low-voltage devices suffer from degraded transient response or large footprint when a capacitorless or dominant-pole compensated low-dropout (LDO) regulator biases the driver. Due to the self-stabilizing nature, the proposed stacked mosfet driver (SMD) technology effectively drives the power stage and greatly reduces the noise at the switching nodes for low cross ...
