Abstract
The present invention relates to multi-cell regulator systems and methods. Power supply delivery and regulation is provided to electronic devices disposed on a PCB board. A voltage regulator cell system is provided for a respective voltage regulation cell region, such that the supply voltage is regulated over the area of the power plane and the ground plane. The voltage regulator cell systems are provided with feedback loops at corresponding voltage regulation cell regions, which are compared with a reference voltage to adjust for difference errors. Various systems and methodologies are provided to obtain a desired reference voltage. Power supply delivery performance is further improved by accurate current sharing between voltage regulator cell systems.
