Patent attributes
A distributed power management circuit is provided. In embodiments disclosed herein, the distributed power management circuit can achieve multiple performance enhancing objectives simultaneously. More specifically, the distributed power management circuit can be configured to switch a modulated voltage from one voltage level to another within a very short switching window, reduce in-rush current required for switching the modulated voltage, and minimize a ripple in the modulated voltage, all at same time. As a result, the distributed power management circuit can be provided in a wireless device (e.g., smartphone) to enable very fast voltage switching across a wide modulation bandwidth (e.g., 400 MHz) with reduced power consumption and voltage distortion.
