Patent ID: 10141844

Abstract:
The present disclosure shows ways to use multiple “integrated voltage regulator (IVR) units” to offer IVRs that can cover a wide range of specifications without having to design separate IVRs for different specifications. Instead of designing separate IVRs and paying for separate mask sets for IVRs targeting different specifications (e.g., different design and mask sets for 1 A IVR, 5 A IVR), the disclosed embodiments present ways to design and fabricate large numbers of the same unit IVRs (e.g., 1 A IVR) and decide how many of them to use post-fabrication to deliver different current specifications (e.g., use five 1 A unit IVRs for 5 A, use ten 1 A unit IVRs for 10 A). These disclosed embodiments reduce the mask cost of fabricating IVRs for different specifications and reduce design time by focusing on a single unit IVR.
