Abstract :
This paper presents a 2GS/s 10-bit CMOS digital-to-analog converter (DAC). This DAC consists of a unit current-cell matrix for 6MSBs and another unit current-cell matrix for 4LSBs, trading off between the precision and size of the chip. The current mode logic (CML) is used to ensure high speed, and a double centro-symmetric current matrix is designed by the Q2 random walk strategy in order to ensure the linearity of the DAC. The DAC occupies 2.2 times 2.2 mm2 of die area, and consumes 790mw at a single 3.3V power supply
