Semiconductor system with voltage regulator and method for operating the same

A semiconductor system, comprising:

• a voltage regulator, configured to regulate an output voltage for a plurality of loading circuits, comprising:
• an amplifier, configured to provide a sinking current and a sourcing current to the plurality of loading circuits;
• and
• a biasing circuit, configured to dynamically control the amplifier in response to a comparison between the output voltage and a reference voltage, wherein the amplifier is configured to provide the sinking current when the output voltage is greater than the reference voltage, and the amplifier is configured to provide the sourcing current when the output voltage is lower than the reference voltage;
• a first capacitor, electrically connected to the voltage regulator to stabilize the sinking current from the loading circuits;
• and
• a second capacitor, electrically connected to the voltage regulator to stabilize the sourcing current to the loading circuits.

A method for operating a semiconductor system, comprising:

• controlling, by a voltage regulator, a sinking current and a sourcing current associated with a plurality of loading circuits;
• stabilizing, by a first capacitor, the sinking current transmitted from a high-voltage portion of the loading circuits, wherein the first capacitor is external to the loading circuits;
• stabilizing, by a second capacitor, the sourcing current transmitted to a low-voltage portion of the load circuits, wherein the second capacitor is external to the loading circuits;
• decreasing noise of the high-voltage portion by a third capacitor embedded within the loading circuits;
• and
• decreasing noise of the low-voltage portion by a fourth capacitor embedded within the loading circuits.
