Abstract
A digital-to-analog converter (DAC) device includes a DAC circuitry. The DAC circuitry includes a first DAC circuit and a second DAC circuit. The first DAC circuit is configured to generate a first signal according to a plurality of least significant bits of an input signal. The second DAC circuit is configured to output a second signal according to a plurality of most significant bits of the input signal. A first turn-on time of at least one current source circuit in the first DAC circuit is configured to set the first signal.
