Abstract

Disclosed are an apparatuses and methods for minimum energy tracking loop that includes an oscillator to imitate a threshold path of a load system and automatically adjust a clock frequency as a supply voltage to the load system is changed, a voltage regulator configured to supply a power, an energy sensing unit which is connected to the oscillator and the voltage regulator and calculates a proportional energy proportional to a total energy consumed by the load system at a specific supply voltage, a minimum energy finder to find a minimum energy point of the load system by monitoring the calculated proportional energy proportional to the total energy at a plurality of supply voltages, a buck converter to supply a power to the load system with a supply voltage at which the load system operates with a minimum energy when the minimum energy point is found in the minimum energy finder.
