Summary: | Increases in current drawn from power supply nodes in a computer system can result in unwanted drops in the voltages of the power supply nodes until power supply circuits can compensate for the increased load. To lessen the effects of increases in load currents, a decoupling circuit that includes a diode may be coupled to the power supply node. During a charge mode, a control circuit applies a current to the diode to store charge in the diode. During a boost mode, the control circuit can couple the diode to the power supply node. When the voltage level of the power supply node begins to drop, the diode can source a current to the power supply node using the previously stored charge. The diode may be directly coupled to the power supply node or be part of a switch-based system that employs multiple diodes to increase the discharge voltage. |
