Patent ID: 8536935

Claim:
A system for uniform power regulation of an integrated circuit, comprising: each region of a plurality of regions of the integrated circuit including: 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 configured to provide a gating voltage; at least one driver circuit coupled to receive the gating voltage provided by the comparison circuit and coupled to a first supply voltage, the at least one driver circuit configured to provide a respective regulated voltage responsive to the gating voltage, wherein the at least one driver circuit includes: a pull-up transistor having a first source/drain coupled to the first supply voltage, a second source/drain coupled to the respective regulated voltage, and a gate coupled to the gating voltage; and a leakage transistor having a first source/drain coupled to the respective regulated voltage and a second source/drain coupled to a second supply voltage, the second supply voltage being equal to a ground voltage; and a feedback adjustment circuit having an input coupled to the respective regulated voltage of the at least one driver circuit and an output coupled to the second input of the comparison circuit, the feedback adjustment circuit configured to trim the respective regulated voltage by a region-specific trim value and output the trimmed regulated voltage as the feedback voltage on the output.
