Abstract
Power management for an integrated circuit. One example embodiment is a method of operating a portable audio device including: reading, by a supply controller, a logic speed measurement from a logic gate delay line, the supply controller and the logic gate delay line implemented on a semiconductor substrate; computing, by the supply controller, a speed margin based on the logic speed measurement; creating, by the supply controller, a value indicative of a modified voltage level, the creating based on the speed margin; and modifying, by a main voltage converter on the semiconductor substrate, an output voltage responsive to the value indicative of the modified voltage level.
