Abstract
A droop reduction circuit on a die includes a voltage detector circuit to detect voltage droop in a supply voltage received by a first load. The droop reduction circuit further includes a driver controller circuit to drive power switch (PSH) banks in response to detection of the voltage droop. Each of the PSH banks includes at least one power switch having an input terminal, a gate terminal, and an output terminal. The input terminal is to receive a secondary voltage, which is higher than the supply voltage and is also received by a second load on the die. The gate terminal is to receive a drive signal from the driver controller, and the output terminal is to pull up the voltage droop in the supply voltage.
