摘要：
An output capacitor-less low-dropout (LDO) regulator based on flipped voltage follower (FVF) for system-on-chip (SoC) application is presented. With a common-gate amplifier and two-pole system, it evidently simplifies the architecture of the LDO regulator and achieves the stability more easily. Implemented in SMIC 55nm CMOS, the proposed LDO regulator only consumes 15 mu A net current from 1.5V power supply, with a minimum dropout voltage of 200 mV. With 16pF total compensation capacitance, it can provide 0-30mA load current with a load capacitance range of 0-300pF.
