Abstract

A design structure for intrinsic RC power distribution for noise filtering of analog supplies. The design structure is embodied in a machine readable medium for designing, manufacturing, or testing an integrated circuit. The design structure includes a voltage regulator; a variable resistor coupled to the voltage regulator; and a performance monitor and control circuit providing a feedback loop to the variable resistor.
