Abstract

See full text

Hybrid digital-to-analog converter and method thereof are provided. The hybrid digital-to-analog converter (DAC) includes a data processor, at least one first type DAC, at least one second type DAC, and an output circuit. The data processor processes an input digital signal to output at least one of first and second digital signals which are related to a higher bit portion and a lower bit portion of the input digital signal, respectively. If the data processor outputs the first digital signal to the first type DAC, the first type DAC converts the first digital signal. The at least one second type DAC receives and converts the second digital signal outputted from the data processor. The output circuit receives at least one output signal of the first and the second type DACs to output an output analog signal.
