Design and implementation of high-performance CMOS D/A converter

In this paper we present the design and implementation of a high-performance digital-to-analog converter in a 3.3-V 0.6-um digital CMOS process. To reduce glitch energy and maintain speed and small chip area, we combine segmentation and binary weighting, as well as clock all the input data before driving bit switches and equalize the delay for all the circuit blocks. We also present a new layout style, which enhances matching and further reduces glitch energy. Measurement results are also included.
