Abstract
A circuit is disclosed. The circuit includes a power supply node and a system configured to receive current from the power supply node at a regulated voltage and to generate one or more control signals indicating an anticipated change in the current. The circuit also includes a voltage regulator configured to provide the current to the power supply node and to drive the power supply node with the regulated voltage, where the value of the regulated voltage is based at least in part on the one or more control signals.
Claims20
A circuit, comprising:
- a power supply node;
- a system configured to receive a load current from the power supply node at a regulated voltage and to generate one or more control signals indicating an anticipated change in the load current;
- and
- a voltage regulator configured to provide the load current to the power supply node and to cause a voltage of the power supply node to be the regulated voltage, wherein the voltage regulator is configured to change a value of the voltage of the power supply node in response to the one or more control signals, wherein the value of the voltage of the power supply node is changed prior to an actual change in the load current corresponding with the anticipated change in the load current.
