摘要:
A digital-to-analog converter is provided. The digital-to-analog converter comprises an input configured to receiving a first digital control code for controlling a plurality of digital-to-analog converter cells. Further, the digital-to-analog converter comprises a code converter circuit configured to converter the first digital control code to a second digital control code. Further, the digital-to-analog converter comprises a shift code generation circuit configured to generate a shift code based on a code difference between the first digital control code and a third digital control code. The digital-to-analog converter additionally comprises a bit-shifter circuit configured to bit-shift the second digital control code based on the shift code in order to obtain a modified second digital control code. The digital-to-analog converter comprises a cell activation circuit configured to selectively activate one or more of the plurality of digital-to-analog converter cells based on the modified second digital control code. Each activated digital-to-analog converter cell is configured to output a respective cell output signal. Further, the digital-to-analog converter comprises an output configured to output an analog output signal based on the cell output signals.
