Abstract

In this paper, an ultra-high-speed, differential current-steering mode 10-bit D/A converter is presented. The converter consists of 8-channel time division multiplexer, 5-31 Â¿thermometerÂ¿ decoder, fast current conversion switch, constant current source array, and other units, is processed in 0.35 Â¿m SiGe BiCMOS standard process technology, and has a data fresh rate of up to 1 GSPS. First, the circuit principle and the structure and design methodology of different units are described. Then, the simulation results of circuit are given. Finally, 10-bit D/A converter are tested and analyzed. The results show that the 10-bit D/A converter features the high resolution, the fast speed, and the high universality.
