Abstract

In certain aspects, a system includes an amplifying circuit having an input and an output, a high-pass filter coupled between a gate of a pass transistor of a low dropout (LDO) regulator and the input of the amplifying circuit, and a metal-oxide-semiconductor (MOS) capacitor coupled between the output of the amplifying circuit and the gate of the pass transistor.
