Abstract
A digital-to-analog converter (DAC) is provided for converting an (X+Y)-bit input word, which includes an X-bit MSB subword and a Y-bit LSB subword, into a current signal. The DAC has an X-bit voltage DAC section and a Y-bit current DAC section. The X-bit voltage DAC section generates an intermediate voltage corresponding to the X-bit MSB subword. The Y-bit current DAC section generates a reference current corresponding to the intermediate voltage and outputs the current signal derived by multiplying the reference current by a factor corresponding to the Y-bit LSB subword. In addition, a method for digital-to-analog conversion of an (X+Y)-bit input word into a current signal is also provided.
