ABSTRACT:
The invention proposes noise suppression circuits that are assembled together with capacitors on a CPU package. Charge is conveyed from the capacitors dedicated to the active noise suppression function through electrical circuit pathways such as controlled electronic switches integrated into a semiconductor substrate. These circuit pathways connect to the capacitor terminals through the package of the active noise suppression semiconductor chip. The circuits within the active device may be any combination of semiconductor switches and/or voltage regulators, and may also contain voltage and current sensing circuitry. The charge transfer switches are designed with control circuitry that dynamically modulate the turn-on threshold voltage of the switches and maintain the switches at an operating point very close to actual turn-on. These enhancements ensure very fast turn-on action for the switches improving voltage droop suppression capability.
