Abstract

An apparatus for providing on-chip voltage-regulated power includes a switched capacitor voltage conversion circuit that receives an elevated power demand signal and operates at a base rate when the elevated power demand signal is not active and at an elevated rate when the elevated power demand signal is active. The switched capacitor voltage conversion circuit comprises an auxiliary set of transistors that are disabled, when the elevated power demand signal is not active and enabled, when the elevated power demand signal is active. The apparatus may also include a droop detection circuit that monitors a monitored power signal and activates the elevated power demand signal in response to the monitored power signal dropping below a selected voltage level. The monitored power signal may be a voltage input provided by an input power supply for the switched capacitor voltage conversion circuit. A corresponding method is also disclosed herein.
