Abstract
A method for reducing noise in an output of a voltage regulator at frequencies above a closed loop bandwidth, by providing a noise injection path for injecting external noise into the voltage regulator, where the noise injection path becomes active at the frequencies above the closed loop bandwidth, where the noise injection path reduces the noise in the output of the voltage regulator.
