一种具有电源纹波抵消和极点跟踪补偿的自适应偏置无输出电容低压差线性稳压器

This article presents an adaptively biased output-capacitor-free low-dropout regulator that achieves high power supply rejection for wearable biomedical system-on-chips (SoCs). Adaptive biasing is implemented to achieve both fast transient responses and high power conversion efficiency, and the common-gate current feedback loop enhances the dc gain of the error amplifier by 10 dB. The proposed sup...
