Voltage generating system

Abstract

A voltage generating system has a first voltage generating device for generating a plurality of voltages between a maximum voltage and a minimum voltage as a first set of voltages, and a second voltage generating device for generating a plurality of voltages between the maximum voltage and the minimum voltage as a second set of voltages, the second set of voltages being different from the first set of voltages. The first voltage generating device generates the maximum voltage, and supplies the first set of voltages and the maximum voltage to the second voltage generating device. The second voltage generating device generates the minimum voltage, and supplies the second set of voltages and the minimum voltage to the first voltage generating device. The first and second voltage generating devices each select a voltage from the first and second sets of voltages, and output the selected voltage.
