Abstract :
In this paper we use the load current of the CPU as decision of the working state of the PC is either a heavy load or a light load. Based on the voltage specification of each device on the PC motherboard, we use the current control for dynamic voltage scaling (IREF-DVS) regulator to provide different voltages for each device. When the PC has a light load we can decrease the operating voltage of each device to the minimum voltage, and with a heavy load this design can increase it to the maximum voltage to improve the performance.
