ENERGY-RECYCLING FOR A COST-EFFECTIVE PLATFORM TO OPTIMIZE ENERGY EFFICIENCY FOR LOW POWERED SYSTEM

摘要

A system including: a voltage converter configured to convert a voltage from a power source to a different voltage; a memory coupled to the voltage converter; a digital logic circuit; and a level shifter coupled between the memory and digital logic circuit; wherein leakage current from the memory is stored in a capacitance in the digital logic circuit, wherein the voltage converter is further coupled to a node between the memory and digital logic circuit, and wherein the voltage converter is configured to: monitor a voltage at the node wherein the node has a desired operating voltage value; and adjust the voltage at the node when the voltage at the node varies from the desired operating voltage value.
