Integrated power solution for system on chip applications

摘要

A centralized power supply system for a multi-system on chip device includes: an external power supply for supplying power to the device; a centralized DC generator macro having generator components for receiving the external power supplied and generating therefrom one or more power supply voltages for use by surrounding system macros provided on the multi-system chip, the centralized DC generator macro further distributing the generated power supply voltages to respective system macros. A noise blocking structure is provided that surrounds the centralized DC generator system and isolates the centralized DC generator system from the surrounding system macros.
