Abstract: A voltage resolution adjustment system and method increase voltage resolution of an output voltage of a processor from a first voltage resolution to a second voltage resolution. The system includes a processing module, a voltage-dividing module, and an amplifying unit. The processing module generates a first voltage of a first voltage resolution. The voltage-dividing module increases the first voltage of the first voltage resolution to a second voltage of a second voltage resolution. The amplifying unit increases the second voltage to a third voltage (i.e., the output voltage). After comparing the third voltage and the first voltage and detecting a voltage difference therebetween, the processing module generates a control signal for changing a voltage partitioning ratio of the voltage-dividing module to render the third voltage and the first voltage equal, wherein the third voltage is of the second voltage resolution.
