Abstract
A digital-to-analog converter is coupled to a first voltage source and used for converting a digital input into an analog output. The DAC includes a voltage booster providing a first gate-source voltage and a second gate-source voltage to generate a voltage of a first level according to the first voltage source and the first gate-source voltage, and to generate a voltage of a second level according to the voltage of the first level and the second gate-source voltage; and a current-guiding circuit selectively receiving the voltage of the first level or the second level according to the digital input to generate the analog output. The first level and the second level vary with the first voltage source.
