A capacitor-free CMOS LDO regulator with AC-boosting and active-feedback frequency compensation
交流提升与有源反馈补偿的无片外电容CMOS低压差稳压器

A capacitor-free CMOS low-dropout (LDO) regulator for system-on-chip (SoC) applications is pre- sented. By adopting AC-boosting and active-feedback frequency compensation (ACB-AFFC), the proposed LDO regulator, which is independent of an off-chip capacitor, provides high closed-loop stability. Moreover, a slew rate enhancement circuit is adopted to increase the slew rate and decrease the output voltage dips when the load current is suddenly switched from low to high. The LDO regulator is designed and fabric...
