Wide range full-scale current configurable current-steering digital-to-analog converter (dac)

A method for digital-to-analog conversion, comprising:

• receiving a digital input code at an input of a digital-to-analog converter (DAC) comprising a plurality of DAC cells;
• and
• generating, via the DAC, an analog output signal based on the digital input code, wherein each DAC cell in a set of the DAC cells comprises:
• a first current source coupled to an output of the DAC cell;
• a second current source coupled to the output of the DAC cell;
• a resistive network including a plurality of resistive elements coupled between a voltage rail and the first current source, wherein the resistive network is coupled to the first current source and the second current source;
• and
• a plurality of switches coupled between the voltage rail and nodes of the resistive network.
