In this paper, an internally compensated dual-summed flipped voltage follower (FVF) low drop-out (LDO) regulator is proposed. This LDO uses a small miller capacitance (MC) and an active feed-forward compensation (AFFC) to internally stabilize the feedback loop. The active feed-forward compensator shifts an RHP zero of the miller capacitance to the load-dependent LHP zero. A simple RC high-pass filter enhances the overshoot transient response of the LDO and stabilizes the feedback loop further with increased phase margin. This LDO achieves settling time of $110\mathrm{ns}$ during overshoot and $32\mathrm{ns}$ during undershoot with edge time of $25\mathrm{ns}$.

具有有源前馈补偿的双和翻转电压跟随器LDO稳压器

本文提出了一种内部补偿双和翻转电压跟随器（FVF）低压降（LDO）调节器。该LDO使用小米勒电容（MC）和有源前馈补偿（AFFC）来内部稳定反馈环路。有源前馈补偿器将米勒电容的RHP零移位到与负载有关的LHP零。一个简单的RC高通滤波器可增强LDO的过冲瞬态响应，并通过增加相位裕量来进一步稳定反馈环路。该LDO的建立时间为$110\mathrm{ns}$ 在过冲和 $32\mathrm{ns}$ 在欠冲期间，边沿时间为 $25\mathrm{ns}$。
