Field: Control (Instruments)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A Low-Dropout voltage regulator (LDO) comprising:
an amplifier supplied with a voltage reference (VREF) input, the amplifier configured to produce a source current to or a sinking current from a load; and
a decoupling capacitor, connected to an output of the amplifier, configured to decouple a high-edge ground (HGND) from a power source, the decoupling capacitor including a first capacitor and a second capacitor attached with the load, wherein the first capacitor is a pure Metal-Oxide-Metal (MOM) capacitor (CMOM) and the second capacitor is a core P-type Metal Oxide Semiconductor Capacitor (PMOSCAP), wherein one or more Metal Oxide Semiconductor Field Effect Transistors (MOSFETS) is placed beneath the CMOM to get a highest capacitance density.
