| Abstract: | Based on complementary bipolar technology, a novel high-speed 12-bit current output D/A converter with binary current source weighted structure is proposed in this paper. Compared to CMOS technology, the architecture of D/A converter is simple while its performance is excellent. The result from HSPICE simulation indicates that the full-scale output current is 10.24 mA, and the full-scale setup time is less than 25 ns. |
