Abstract :
On-chip decoupling capacitors are actively switched to suppress resonance in the power distribution system of a microprocessor. With this scheme, charge storage capacity is amplified, while instantaneous monitoring of rail activity and dynamic control of the switching response provide bandlimited on-chip voltage regulation.
