Abstract
A digital-to-analog converter (DAC) for generating an analog output voltage according to a digital input value includes a plurality of pulse width modulation (PWM) units and a voltage generating unit. The digital input value includes a plurality of bit segments. The plurality of PWM units generates a plurality of PWM signals according to the plurality of bit segments of the digital input value. The voltage generating unit is coupled to the plurality of PWM units and generates the analog output voltage according to the plurality of PWM signals.
