Abstract
A digital-to-analog converter includes an amplifier, a voltage relaxation circuit, a base current source, a first weighting current source, and at least one second weighting current source. The amplifier receives a reference voltage and a feedback voltage, and generates an output voltage according to the reference voltage and the feedback voltage. The base current source is coupled to an output end of the amplifier through the voltage relaxation circuit, and is configured to generate an adjustable base current. The first weighting current source generates an adjustable first weighting current between a reference ground end and one of a current load and the voltage relaxation circuit according to a first bit of input data. The second weighting current source generates at least one second weighting current according to at least one second bit of the input data.
