Patent ID: 8736353

Claim:
A system for regulating voltage in a localized portion of an integrated circuit, comprising: an integrated circuit having a voltage input, said integrated circuit comprising at least a localized region that is less than all of said integrated circuit, said localized region requiring a local voltage level; a voltage selector establishing a target voltage level for said localized region; a first comparator comparing said target voltage level to said local voltage level and generating a pull up control signal when said local voltage level is below said target voltage level; a second comparator comparing said target voltage level to said local voltage level and generating a pull down control signal when said local voltage level is above said target voltage level; a pull up device responsive to said pull up control signal, said pull up device increasing said local voltage level when said pull up control signal is asserted; and a pull down device responsive to said pull down control signal, said pull down device decreasing said local voltage level when said pull down control signal is asserted.
