Abstract :
A poly-resistor 12-bit D/A converter is described in this paper. The D/A converter was processed in XC06 process technology. Since the trimming process isn¿t used, the chip features the low cost. The linearity of the circuit was 0.3 LSB, and the settling time was 200 ns. The design and layout of the circuit was improved and optimized, and a novel cross layout scheme was especially adopted, thus resolving the issue on degeneration of D/A converter performance caused by the long-distance effect and the plastic packaging stress.
