Digital-to-analog converter and method for digital-to-analog conversion

A method for digital-to-analog conversion,

• wherein at least a portion of a first source current that flows through a first current source of a first number N of current sources flows to a converter output,
• wherein each of the first number N of current sources is coupled via a first switching arrangement either to the converter output, a dummy output or to an input current terminal of a first current divider,
• wherein each of a second number K of output current terminals of the first current divider is coupled via a second switching arrangement either to the converter output, the dummy output or to an input current terminal of a second current divider, and
• wherein each of a third number P of output current terminals of the second current divider is coupled to the converter output and/or the dummy output.

A digital-to-analog converter, comprising

• a converter output and
• a cascade structure that is coupled to the converter output and comprises a number L of segmentation levels,
• wherein a first segmentation level of the number L of segmentation levels comprises a first number N of current sources and a first switching arrangement,
• wherein a second segmentation level of the number L of segmentation levels comprises a first current divider with an input current terminal and a second number K of output current terminals and a second switching arrangement,
• wherein a third segmentation level comprises a second current divider and a third switching arrangement, and
• wherein the first number N of current sources is exactly 2, the second number K of output current terminals of the first current divider is exactly 2 and a third number P of output current terminals of the second current divider is exactly 2.
