摘要
本文提出了一种低差(LDO)稳压器，可以提供高达0.3A的输出电流，具有高电源抑制(PSR)。提出的bgr -递归LDO设计具有PSR增强前馈，提高了PSR，同时消耗了$\le 50 \mu \mathrm {A}$的低静态电流。在最先进的ldo中，该芯片在$0.5 \mu \mathrm {m}$ CMOS中制造，在100Hz至0.1MHz的频率范围内实现了102至80db的最高PSR，电流效率为99.98% and shows the best FoM of 11ps in the transient response performance.
A 300mA BGR-Recursive Low-Dropout Regulator Achieving 102-to-80dB PSR at Frequencies from 100Hz to 0.1MHz with Current Efficiency of 99.98%
This paper presents a low-dropout (LDO) regulators that can supply up to 0.3A output current with high power supply rejection (PSR). The proposed BGR-recursive LDO design with PSR-boosting feedforward improves the PSR while consuming a low quiescent current of $\le 50 \mu \mathrm {A}$. Among the state-of-the-art LDOs, the proposed chip fabricated in $0.5 \mu \mathrm {m}$ CMOS achieves the highest PSR of 102-to-80dB in the frequency range from 100Hz to 0.1MHz with a current efficiency of 99.98% and shows the best FoM of 11ps in the transient response performance.
