Abstract
A digital-to-analog converter (DAC) system includes a DAC and a current trimming module. The DAC includes a plurality of segments and a plurality of drivers. Each of the plurality of segments receives driver signals from a respective one of the plurality of drivers, receives segment currents from a respective one of a plurality of segment current sources, and generates an output current based on the driver signals and the segment currents. The current trimming module stores a plurality of trim coefficients and adjusts respective threshold voltages associated with the plurality of segment current sources based on the plurality of trim coefficients.
