Abstract :
This brief discusses the economical design of a 14-b current-steering digital-to-analog converter (DAC) macrocell for integration with other analog and digital macrocells in a system-on-chip (SOC). The DAC design is targeted for a standard 0.13-μm six-metal single-poly CMOS process. A novel algorithm sets the switching order of individual current sources and minimizes systematic mismatch errors. The design approach minimizes total fabrication cost of the SOC without a loss to specified DAC design requirements. Total macrocell design area is 2.9 mm2.
