Abstract
ABSTRACT
This paper presents a novel design for a 10 bit DAC. The design is to be integrated in a direct
digital frequency synthesizer (DDFS). The design consists of three main modules, a nonlinear
course DAC, a linear fine DAC, and a nonlinear interpolation DAC. Each of these modules
contributes in enhancing the DAC performance. The DAC is then integrated, and simulated
using Mentor Graphics Tools. The simulation was done using a 3.3V, 0.35u CMOS
technology. The design has an advantage over the published DACs in its simplicity and
repeatability. The design operates at higher output frequency with considerable spectral
purity.
