An output-capacitorless low-dropout regulator (OCL-LDO) using split-length current mirror compensation and overshoot/undershoot reduction circuit are presented in this paper. At a supply of 1.5 V and a quiescent current of 8.2 µA, the proposed scheme can support a maximum load current of 50 mA. The proposed OCL-LDO has a range of output voltage from 0.8 to 1.25 V with 1.5 V supply. The proposed regulator is designed and post-simulated by UMC 55-nm standard CMOS process. The simulation results show that the proposed scheme is stable in different temperatures and process corners with 10 pF output capacitor. The maximum value of overshoot and undershoot is 69.0 mV and 91.5 mV, respectively.

本文提出了一种使用分流电流镜补偿和过冲/下冲减少电路的无输出电容器的低压差稳压器（OCL-LDO）。在1.5 V的电源电压和8.2 µA的静态电流下，该方案可以支持50 mA的最大负载电流。所提议的OCL-LDO在1.5 V电源下的输出电压范围为0.8至1.25V。拟议的稳压器是通过UMC 55纳米标准CMOS工艺设计和后仿真的。仿真结果表明，采用10 pF输出电容器，该方案在不同温度和工艺角下均稳定。过冲和下冲的最大值分别为69.0 mV和91.5 mV。
