Abstract: A number of unit cells of a digital-to-analog converter (DAC) may be simultaneously activated to generate an analog signal. However, while each unit cell may be generally the same, there may be variations such as non-linearity or noise in the analog output depending on which unit cells are activated for a given digital signal value.

The fill order may be set by a fill controller via the fill-selection signal to account for manufacturing variations, gradients in the supply voltage, output line routing, and/or environmental factors such as temperature.

Abstract: A number of unit cells of a digital-to-analog converter (DAC) may be simultaneously activated to generate an analog signal according to a decoded digital signal. However, while many unit cells may be generally the same, there may be variations in the gains associated with each unit cell (e.g., based on the locations of the activated unit cells within a unit cell array) amounting to a gain gradient that may cause error in the analog output.
