一种基于电流估计算法粗调环路的快速瞬态全集成数字低压差线性稳压器

In this brief, a fully-integrated output-capacitor-free (OCF) digital low-dropout regulator (DLDO) is proposed utilizing a current-estimation algorithm (CEA)-based coarse loop controller to achieve fast voltage droop (${V}_{Droop}$) recovery with improved line and load regulations. The proposed CEA-based controller quickly determines the target output switch-code by estimating the current-voltage ...
