Abstract :
In this paper a novel design of an 11 bit digital-to-analog converter (DAC) is introduced. The design is to be integrated in a direct digital frequency synthesizer (DDKS). The designing of a DAC is critical due to its poor performance and low speed. The proposed design consists of three modules, a linear DAC, a nonlinear DAC and a nonlinear interpolation DAC. Each module contributes in enhancing the DAC performance. The DAC is integrated and simulated using Mentor Graphic tools. The simulation was done using a 3.3V, 0.35mu CMOS technology
