随着工艺的发展及许多SOC产品及便携式电子产品的工作电压不断下降，省电观念越来越引人注目，对提供电源的芯片要求越来越高。针对供电电源日趋低压化，以及节能环保意识成为各个国家及众多消费者的共识，低电源电压下能工作且具有低功耗成为线性稳压器的发展趋势。本文提出了一种输出电压1.5V，输入电压可以低至1.7V的情况下稳定工作并能提供300mA电流的低压差线性稳压器电路，整个线性稳压器电路的静态电流低于40uA。与传统的低压差线性稳压器相比，本文设计的低压差线性稳压器电路系统提出了利用有源前馈米勒补偿（AFFC）与共源共栅米勒补偿相结合的新颖动态米勒补偿结构，这种补偿结构下的电路系统具有恒定的带宽（1...With the developments of electronics and telecommunication, portable electronical products become more and more popular. The developments of power management technologies and applications are rapidly promoted. A high-accuracy, micro power and low-dropout (LDO) voltage regulator is presented in this paper. A novel compensation structure that using the Active-Feedback Frequency Compensation (AFF...学位：工程硕士院系专业：信息科学与技术学院电子工程系_仪器仪表工程学号：X20043000
