Abstract
A system for uniform power regulation of an integrated circuit is disclosed. In each of a plurality of regions, the system includes a comparison circuit having a first input coupled to receive a reference voltage and a second input coupled to receive a feedback voltage. The comparison circuit provides a gating voltage to a driver circuit that is coupled to a first supply voltage. The driver circuit is configured to provide a regulated voltage responsive to the gating voltage. A feedback adjustment circuit is configured to trim the regulated voltage by a region-specific trim value and output the trimmed regulated voltage as the feedback voltage on the output.
