Abstract
A system and method for adaptively providing a power supply voltage. The system includes an input/output subsystem configured to receive a first voltage, an analog subsystem configured to receive a second voltage and coupled to the input/output subsystem, a first digital subsystem configured to receive a third voltage and coupled to the input/output subsystem, and a second digital subsystem configured to receive a fourth voltage and coupled to the input/output subsystem, the first digital subsystem, and the analog subsystem.
Claims12
A system for adaptively providing a power supply voltage, the system comprising:
- an input/output subsystem configured to receive a first voltage;
- an analog subsystem configured to receive a second voltage and coupled to the input/output subsystem;
- a first digital subsystem configured to receive a third voltage and coupled to the input/output subsystem;
- a first adaptive power supply configured to receive an input voltage and generate the third voltage;
- wherein:
- the first digital subsystem is configured to receive a clock signal associated with a clock frequency;
- the first adaptive power supply is further configured to adjust the third voltage based on at least information associated with a comparison of a first frequency and the clock frequency.
