Abstract
Systems and methods provide for the control of a fully-segmented digital-to-analog converter. The selected lead-most current cell of an array in the digital-to-analog converter is addressed individually using a row/column scheme and a decoder. The remaining current cells behind the lead-most current cell are enabled via a ripple enable signal that propagates backwards from the lead-most current cell. The ripple enable signal snakes through the array to enable all the current cells behind the lead-most current cell in a cell-by-cell fashion. The current cells in front of the lead-most current cell are not enabled.
