Claim Text:
1. A voltage generator, for providing a plurality of output voltages having different levels, comprising: a reference block, for providing a plurality of reference voltages according to a supply voltage, comprising: a plurality of digital-to-analog conversion blocks, coupled to the reference block, each receiving the reference voltages and generating a digital-to-analog output voltage according to a digital code, wherein digital-to-analog output voltages generated by the digital-to-analog conversion blocks have different levels, respectively and are used to generate the output voltages; wherein a range of the D/A output voltage generated by a first digital-to-analog conversion block of the digital-to-analog conversion blocks is different from that of the digital-to-analog output voltage generated by a second digital-to-analog conversion block, and the range of the digital-to-analog output voltage generated by the first digital-to-analog conversion block of the digital-to-analog conversion blocks partially overlaps that of the digital-to-analog output voltage generated by the second digital-to-analog conversion block.
