Abstract
An LDO regulator circuit apparatus capable of removing supply voltage noise is disclosed. The LDO regulator circuit apparatus capable of removing supply voltage noise comprises a flipped voltage follower (FVF) regulator circuit unit having a pass transistor Mconfigured to adjust a supply voltage to output an output voltage; an error amplifying circuit unit configured to receive and compare a reference signal (V) and a feedback voltage (V), wherein the feedback voltage is fed back through the output voltage through a feedback loop; a common gate (CG) circuit unit configured to amplify a feedback loop gain of the flipped voltage follower (FVF) regulator circuit unit; and a super source follower circuit unit configured to buffer an output of the CG circuit unit and transmit it to a gate node of the pass transistor (M).
