Abstract
A voltage regulator circuit includes a voltage regulator electrically coupled to a load through an output inductor and operable to regulate a voltage applied to the load, an output capacitor electrically coupled to a node between the inductor and the load, and a charge injection circuit capacitively coupled to the node. The output capacitor is configured to discharge energy stored in the capacitor to the load during step-up transient events at the load and absorb energy from the load during step-down transient events at the load. The charge injection circuit is operable to inject charge onto the output capacitor during the step-up transient events and absorb charge from the output capacitor during the step-down transient events.
